A new approach was developed for environmentally friendly C-C cross-coupling reactions using bi-functional Pd(II)-salen complex-embedded cellulose filter paper (FP@Si-PdII-Salen-[IM]OH). A Pd(II)-salen complex bearing imidazolium [OH]-moieties was covalently embedded into a plain filter paper, then used as an efficient portable catalyst for the Heck, Suzuki, and Sonogashira cross-coupling reactions under environmentally friendly conditions via the filtration method. The catalytic filter paper properties were studied by EDX, XPS, TGA, ATR, XRD, and FESEM analyses. The reactions were catalyzed during reactants filtration over the catalytic filter paper. The modified filter paper was set up over a funnel and the reactants were passed through the catalytic filter paper several times. The effect of reaction parameters including loading of Pd(II)-salen complex, temperature, solvent, and contact time were carefully studied and also the optimal model of conditions was presented by the design expert software. High to excellent yields were obtained for all C-C coupling types with 5 to 8 filtration times. Under optimal conditions, all coupling reactions showed high selectivity and efficiency. Another advantage of the modified filter paper was its stability and reusability for several times with preservation of catalytic activity and swellability.

Novel Schiff bases were synthesized by condensing aromatic amines with pyridoxal-5′-phosphate and characterized by using FT-IR, ¹H NMR, and ¹³C NMR spectroscopic techniques. The resulting Schiff bases were utilized as bidentate ligands, coordinating via imine nitrogen and phenolate oxygen atoms, to stabilize palladium ions. Aryl substituents on imine nitrogen allowed for fine tuning of the stereoelectronic properties of the Schiff bases. The catalytic activity of the selected palladium complexes was investigated in the Suzuki cross-coupling reaction of a series of aryl halides with boronic acids in H₂O/EtOH (1:1). Out of four complexes investigated in the cross-coupling reactions, Pd(L₈)₂, bearing a methoxy substituent on aryl imine, showed the highest activity at low catalyst loading. The scope of the reaction was also investigated with 26 samples.

Nguyen, Kevin;Clement, Helen A.;Bernier, Louise;Coe, Jotham W.;Farrell, William;Helal, Christopher J.;Reese, Matthew R.;Sach, Neal W.;Lee, Jack C.;Hall, Dennis G. research published 《 Catalytic enantioselective synthesis of a cis-β-boronyl cyclobutylcarboxyester scaffold and its highly diastereoselective nickel/photoredox dual-catalyzed Csp³-Csp² cross-coupling to access Elusive trans-β-aryl/heteroaryl cyclobutylcarboxyesters》, the research content is summarized as follows. Chiral cyclobutanes are components of numerous bioactive natural products, and consequently, they have also gained significant attention in medicinal chem. Optically enriched cyclobutylboronates can serve as valuable synthetic intermediates for the synthesis of a broad variety of chiral cyclobutanes through exploiting the versatility of the boronyl functionality. Herein, by using a high-throughput ligand screening approach, an efficient method for the asym. conjugate borylation of a cyclobutene 1-carboxyester was optimized, leading to a highly enantioenriched cis-β-boronyl cyclobutylcarboxyester scaffold (99% ee, >20:1 dr). Of the 118 ligands screened, the Naud family of phosphine-oxazoline ligands was found to be the most effective. Computational modeling of the possible preinsertion complexes shows a large preference for the π-bound Cu(I)-alkene complex where the substrate’s large benzhydryl ester occupies a relatively unhindered quadrant of the chiral ligand in a spatially tight environment that is highly specific for the cyclobutenoate substrate and imparts much lower selectivity with larger ring substrates. The cis diastereoselectivity is proposed to arise from a sterically controlled, irreversible protodecupration step. A highly diastereoselective nickel/photoredox dual-catalyzed Csp³-Csp² cross-coupling of the corresponding trifluoroborate salt with aryl/heteroaryl bromides and cycloalkenyl nonaflates was developed, providing access to a wide diversity of trans-β-aryl/heteroaryl and cycloalkenyl cyclobutylcarboxyesters with an excellent diastereoselectivity and high retention of optical purity (91-99% ee, >20:1 dr). Azaheterocyclic halides, which are notoriously challenging substrates in Pd-catalyzed cross-coupling, are successful with this Ni/photoredox manifold. A stereoconvergent model based on steric factors is proposed for the key carbon-carbon bond forming step, leading to a high diastereoselectivity. Despite the radical nature of the cross-coupling conditions, the flanking carboxyester proved to be a reliable chirality relay group to maintain the stereochem. integrity of the organoboron intermediate. Furthermore, mild oxidation of the carbon-boron bond and extension of the catalytic asym. conjugate borylation reaction to a three-component aldol reaction with an aldehyde afford valuable enantioenriched cyclobutane products.

Meitinger, Nicolas;Mengele, Alexander K.;Nauroozi, Djawed;Rau, Sven research published 《 Pyrimidine-Substituted Hexaarylbenzenes as Versatile Building Blocks for N-Doped Organic Materials》, the research content is summarized as follows. In this work the synthesis of several bis-pyrimidine substituted hexaarylbenzenes (HABs) such as I [R¹ = H, t-Bu; R² = H, t-Bu] furnished with tert-Bu groups at different sites of the four pendant Ph rings was reported. The synthetic procedure was based on modular [4 + 2]-Diels-Alder cycloaddition reactions followed by decarbonylation. Anal. of the solid-state structures revealed that the newly synthesized HABs feature a propeller-like arrangement of the six arylic substituents around the benzene core. Here, the tilt of the aryl rings with respect to the central ring strongly depends on the intermol. interactions between the HABs and co-crystallized solvent mols. Interestingly, by evading the closest proximity of the central ring using an alkyne spacer, the distant pyrimidine ring wais oriented in the coplanar geometry with regard to the benzene core, giving rise to a completely different UV-absorption profile.

We report absolute photoabsorption cross sections for gas-phase 2- and 5-bromopyrimidine in the 3.7-10.8 eV energy range, in a joint theor. and exptl. study. The measurements were carried out using high-resolution vacuum UV synchrotron radiation, with quantum chem. calculations performed through the nuclear ensemble approach in combination with time-dependent d. functional theory, along with addnl. Franck-Condon Herzberg-Teller calculations for the first absorption band (3.7-4.6 eV). The cross sections of both bromopyrimidines are very similar below 7.3 eV, deviating more substantially from each other at higher energies. In the 7.3-9.0 eV range where the maximum cross-section is found, a single and broad band is observed for 5-bromopyrimidine, while more discernible features appear in the case of 2-bromopyrimidine. Several π* ← π transitions account for the most intense bands, while weaker ones are assigned to transitions involving the nitrogen and bromine lone pairs, the antibonding σ*_Br orbital, and the lower-lying Rydberg states. A detailed comparison with the available photo-absorption data of bromobenzene is also reported. We have found significant differences regarding the main absorption band, which is more peaked in bromobenzene, becoming broader and shifting to higher energies in both bromopyrimidines. In addition, there is a significant suppression of vibrational structures and of Rydberg states in the pair of isomers, most noticeably for 2-bromopyrimidine.

The development of a general palladium-catalyzed carbonylative method to synthesize acyl fluorides RC(O)F (R = n-Bu, cyclohexyl, 4-methylphenyl, pyridin-3-yl, etc.) from aryl, heteroaryl, alkyl, and functionalized organic halides RX was described. Mechanistic anal. suggests that the reaction proceeds via the unique, synergistic combination of visible light photoexcitation of Pd(0) to induce oxidative addition with a ligand-favored reductive elimination. These together create a unidirectional catalytic cycle that is uninhibited by the classical effect of carbon monoxide coordination. Coupling the catalytic formation of acyl fluorides with their subsequent nucleophilic reactions has opened a method to perform carbonylation reactions with unprecedented breadth, including the assembly of highly functionalized carbonyl-containing products.
