Radico-catalysis: Possible involvement of a cobalt(II) complex in the free radical reactions of sulfur functions

Abstract

A cobalt(II) complex is paramagnetic and can be coordinated with sulfur functions; the coordination complex delocalizes an unpaired electron from cobalt(II) to the sulfur functions such as thioester and vinyl sulfide. Thus, the generation of partial unpaired electron density on the sulfur functions induces or modifies the reactions of the organo free radical containing the sulfur function.
