Alkenylcopper/zinc reagents

Mixed copper-zinc reagents also react with alkynes to give alkenylcopper species that can undergo subsequent electrophilic substitution. [Pg.695]

A one-pot synthesis of y-butyrolactones such as 85 can be realized via an intermediate aHylic zinc species 86 generated by the homologation of an alkenylcopper reagent obtained by the carbocupration of ethyl propiolate (Scheme 7.30). [Pg.267]
