In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Well-defined palladium(II) complexes for ligand-enabled C(sp3)-alkynylation, published in 2015, which mentions a compound: 18436-73-2, mainly applied to palladium catalyst alkynylation methylquinoline; quinoline methyl alkynylation palladium catalyst, Safety of 4-Chloro-8-methylquinoline.
The first example of ligand-enabled C(sp3)-alkynylation of 8-methylquinoline is reported. The reaction is catalyzed by well-defined Pd(II) complexes. The present C(sp3)-alkynylation has a broad substrate scope as well as functional group tolerance and proceeds efficiently under mild conditions.
From this literature《Well-defined palladium(II) complexes for ligand-enabled C(sp3)-alkynylation》,we know some information about this compound(18436-73-2)Safety of 4-Chloro-8-methylquinoline, but this is not all information, there are many literatures related to this compound(18436-73-2).
