SO 2 F 2 mediated cascade dehydrogenative Morita-Baylis-Hillman reaction of the C(sp 3 )-H of primary alcohols with the C(sp 2 )-H of electron-deficient olefins for the assembly of allylic alcohols.

A cascade dehydrogenative Morita-Baylis-Hillman reaction of the C(sp 3 )-H of primary alcohols with the C(sp 2 )-H of electron-deficient olefins for forming allylic alcohols mediated by SO 2 F 2 was developed. This method provides a mild process for the preparation of allylic alcohol moieties without the requirement of transition metals.
