✦ Synopsis

Stereospecifically generated vinylcopper(1) compounds are very easily accessible by addition of opganoheterocupmtes [RCuBrjMgX to 1-alkynes in diethyl ether 1,2 3 or tetrahydrofuran ( THF ) . Also organohomocuprates [RCuR]MgX are suitable reagents for the stereospecific conversion of l-alkynes into vinylic cuprates in the solvent THF 4 :
