Primary α-acetylenic alcohols undergo regio- and stereo-specific additiions of Grignard reagents in the presence of cuprous halides. These reactions yield γ-functionally substituted vinylmagnesium compounds. With secondary and tertiary alcohols, the course of the reaction depends on the nature of alcohol and Grignard reagent.
