Photoredox and Cobalt Co-catalyzed C(sp2)-H Functionalization/C-O Bond Formation for Synthesis of Lactones Under Oxidant- and Acceptor-Free Conditions

Abstract

An practical photoredox and cobalt co-catalyzed C(sp2)-H functionalization/C-O bond formation is described herein, with dihydrogen as the only byproduct. A variety of lactone products can be successfully constructed under oxidant- and acceptor-free conditions with good functional group tolerance and high yield. This protocol also provides a facile route to remote hydroxylated arene and chromene.
