Application of 591-54-8. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 4-Aminopyrimidine, is researched, Molecular C4H5N3, CAS is 591-54-8, about Bidentate geometry-constrained iminopyridyl nickel-catalyzed synthesis of amines or imines via borrowing hydrogen or dehydrogenative condensation. Author is Jiang, Yong; Hu, Miao; Sun, Nan; Hu, Baoxiang; Shen, Zhenlu; Hu, Xinquan; Jin, Liqun.
The efficient Ni-catalyzed N-alkylation of various anilines with alcs. via borrowing hydrogen was reported using a bidentate geometry-constrained iminopyridyl nickel complex as the catalyst. Substituted benzylic alcs. and short/long chain aliphatic alcs. could be applied as the alkylation sources to couple with aromatic and heteroaromatic amines to give a diverse set of N-alkylation outcomes in moderate to excellent yields. The nickel catalytic system was also suitable for aliphatic amines, selectively delivering the corresponding imines via an acceptorless dehydrogenative condensation strategy.
