Catalytic acceptorless dehydrogenation of alcohols using cobalt(I) pincer complexes supported by a P–GeH–P ligand

Abstract

We report a novel P–GeH–P pincer ligand and its cobalt(I) complex, which catalyzes the acceptorless dehydrogenation of alcohols. The Ge–Co complex, featuring a reactive Ge–H bond, shows distinct catalytic properties compared to silicon-based analogues. Moreover, the complex enables the one-pot synthesis of 2-quinolone derivatives, highlighting its potential in organic synthesis.
