Pyrimidines

Category: pyrimidines. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 4-Chloro-8-methylquinoline, is researched, Molecular C10H8ClN, CAS is 18436-73-2, about Cp*CoIII-Catalyzed Alkylation of Primary and Secondary C(sp3)-H Bonds of 8-Alkylquinolines with Maleimides. Author is Kumar, Rakesh; Kumar, Rohit; Chandra, Devesh; Sharma, Upendra.

The cobalt(III)-catalyzed C(sp3)-H bond alkylation of 8-Me quinoline with maleimides is reported. In contrast to the rhodium-catalyzed method, in the current cobalt-catalyzed method, a catalytic amount of acid is used, and importantly, it is also applicable to secondary C(sp3)-H bond alkylation. The developed methodol. is applicable for N-alkyl- and N-aryl-substituted maleimides and unsubstituted maleimides, and it also tolerates the variety of functional groups on the 8-Me quinoline moiety. Atom-economy and high regioselectivity with good to excellent yields of the alkylated products under mild reaction conditions are important features of this method.

Mesoporous materials (MMs) have recently been applied as advanced nanomaterials in different fields (separation, catalysis, adsorption etc.). Synthesis of MMs by chem. surfactants is not ecofriendly. This study focused on the biol. synthesis of a MM by sol-gel method, using a Bacillus subtilis BBK006-mediated surfactant (template) and a precursor (TEOS). The biol. synthesized mesoporous silica nanoparticles (BMSN) were formed at calcination temperatures of 450-600 °C. The BMSN comprise Si and O elements with sp. weights of 56.09% and 42.13% resp., where the at.% was detected to be 41.79% and 55.10%, resp. The phase identity of the synthesized particles (61-300 nm uniform spherical shape; surface area: 8.2616 m2 g-1; pore diameter at 550 °C: 14.8516 nm) was confirmed with wide-angle XRD (10°-81°). A typical type IV isotherm was exhibited (BET curves) following IUPAC nomenclature and confirmed the mesoporous nature. The green-synthesized biosurfactant-mediated BMSN is an environmentally promising material to apply in biomedical science (e.g., antimicrobial activity, drug delivery, CMC, anticancer activity) and oil spill management.

Let’s take a look at the latest research on this compound (cas:591-12-8).

Vapor-phase hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL) was investigated over Al2O3-supported bimetallic Cu-Co catalysts with different Cu/Co weight ratios under ambient H2 pressure. The bimetallic Cu-Co/Al2O3 catalyst with a Cu/Co weight ratio of 8/12 exhibits an excellent catalytic activity and stability: it showed a high GVL productivity of 5.46 kg kg-1cat. h-1 with a GVL selectivity higher than 99% at 250°C for 24 h. In the characterization of the catalysts, powder X-ray diffraction suggests that bimetallic Cu-Co particles on the Cu-Co/Al2O3 catalysts are composed of an alloy.
