Scope of organozinc chemistry 3.1 Nature of the organozinc reagents 

Diorganozinc reagents display an enhanced chemical reactivity compared to alkylzinc halides and furthermore, they are better suited for applications in asymmetric synthesis.38,39 

The zincation of the acetylenic sulfonate 35 furnishes an intermediate lithium alkynylzincate which undergoes a 1,2-migration of a methyl group, followed by a cyclization, leading to a cyclopropylidenylzinc derivative. This intermediate can then be quenched with an aldehyde, resulting in the allylic 

The direct phosphorylation of zinc organometallics provides an efficient
