Peroxide-Free Co(OAc)₂-Catalyzed Radical Addition of sp³ C–H Bonds to Alkynes

Abstract

Cobalt-catalyzed radical addition of C–H bonds adjacent to an oxygen atom towards alkynes is described. The reaction proceeded at 60 °C without using additional radical initiators, and leads to 2-vinyl ether derivatives in good yields.

Key words

cobalt catalysis - radical addition - alkyne - tetrahydrofuran
