Synthesis and crystal structures of two bulky bis(amido)germylenes

Abstract

A new bulky secondary amine, HN(Dip){C(H)Ph2}(Dip = C 6H3Pri2-2,6), has been prepared. This and a related amine, HN(Dip)(Mes)(Mes = mesityl), have been utilized in the formation of bulky lithium amides, which when added to a source of GeCl 2 have yielded two new, bulky bis(amido)germylenes, [Ge{N(Dip)(Mes)}2] and [Ge{N(Dip)[C(H)Ph2]}2], both of which have been crystallographically characterized and shown to be two-coordinate monomers. © 2013 Walter de Gruyter GmbH, Berlin/Boston.
