A Ni/Lewis acid dual-catalytic system has been developed for the Z -selective semihydrogenation of alkynes. Utilizing DMF as both the hydrogen donor and reaction medium, this method affords Z -alkenes in high yield with excellent stereoselectivity under mild conditions. The protocol employs cost-effective and readily available catalysts, and demonstrates broad applicability across a wide range of substrates.
