Aza‐Dipyrrinate Stabilized Compounds with a Low‐Valent Main Group Element

Abstract

AbstractThe possibility of using aza‐dipyrromethene (a‐DPM) ligands to stabilize compounds containing low‐valent main group elements is demonstrated through the isolation of germylenes, a‐DPM(p‐tol)GeCl (2), a‐DPM(Naph)GeCl (6), and a‐DPM(Naph)GeN(TMS)2 (7) (tol=tolyl, Naph=naphthyl). Because of the presence of the a‐DPM ligand, these germylenes exhibit an absorption maximum at around 640 nm, a highly red‐shifted value previously unknown for germylenes.
