A triangular triplatinum(0) complex with bridging germylene ligands: insertion of alkynes into the Pt–Ge bond rather than the Pt–Pt bond†
Abstract
A new triangular triplatinum(0) complex with bridging diphenylgermylene ligands, [{Pt(PMe3)}3(μ-GePh2)3], undergoes insertion of ZCCZ (Z = COOMe) into a Pt–Ge bond. The product contains a μ3-η2(∥)-CZCZ-GePh2 ligand on the Pt3 plane. Two molecules of HCCZ react to afford the Pt3 complex with chelating C, Ge- and Ge, Ge-ligands.
