Synthesis and initial transition metal chemistry of the first PGeP pincer-type germylene

Abstract

A PGeP pincer-type germylene, Ge(NCH₂P^tBu₂)₂C₆H₄, which contains two phosphane groups hanging from the N atoms of an N-heterocyclic germylene fragment, has been isolated for the first time. This compound has already furnished a rich transition metal derivative chemistry (Co, Rh, and Pd) that includes complexes containing bridging P,Ge,P-, chelating P,Ge- and pincer P,Ge,P-ligands.
