Abstract: The NbCl5–EtMgBr-catalyzed reaction of N,N-disubstituted 2-alkynylamines with Et2Zn followed by hydrolysis or deuterolysis affords (2Z)-alkenylamines (reduction products of alkyne) in high yields. The reaction of N,N-disubstituted 2-alkynylamines with Et2Zn catalyzed by the Cp2ZrCl2–EtMgBr system occurs… read more here.
