Abstract

Abstract : We designed an amino imidazoline-2-imine ligand, which stabilized neutral five-membered group 13 carbenoides. These new compound complete the gap between known four- and six-membered triel(i ) carbenoides. Abstract : We present the first cyclic five-membered triel(i ) carbenoides E(AmIm) for E = Ga, In, Tl; AmIm = amido imidazoline-2-imine, which fill the current gap between four- and six-membered triel(i ) carbenoides supported by HGiso and HNacNac. Ga(AmIm) can act as a strong σ-donor ligand in transition metal complexes, while the intermediacy of the Al(i ) carbenoide Al(AmIm) is rationalised based on the isolation of an Al(iii ) insertion product.
