Transition metal catalyzed intermolecular hydroamination of the arylalkynes with aliphatic amine is generally problematic due to the good coordination between amine and metal cation. With the combination of 1,2,3-triazole coordinated gold(I) catalyst (TA-Au) and Zn(OTf)2 cocatalyst, this challenging transformation was achieved with good to excellent yields and regioselectivity. Compared to previously reported methods, this approach offered an alternative catalyst system to achieve this fundamental chemical transformation with high efficiency and practical conditions.

Vinyl chlorides are employed for the first time in palladium catalyzed cross-coupling reactions with amines to furnish imines and enamines. The new methodology has been applied to the synthesis of 2-amino-1,3-butadienes, that could not be achieved from th

The reaction of anions derived from Schiff bases (N-(α-methylbenzylidene)aniline and N-cyclohexylideneaniline) with ethyl iodide or diethyl sulfate in aprotic solvents, in the presence of 18-crown-6, is found to give a high ratio of N/(N+C) or C/(N+C) alkylation when conducted in benzene or in dioxane.
