A triangular triplatinum(0) complex with bridging germylene ligands: insertion of alkynes into the Pt-Ge bond rather than the Pt-Pt bond

A new triangular triplatinum(0) complex with bridging diphenylgermylene ligands, [{Pt(PMe3)}3(μ-GePh2)3], undergoes insertion of ZC≡CZ (Z = COOMe) into a Pt-Ge bond. The product contains a μ3-η(2)(∥)-CZ=CZ-GePh2 ligand on the Pt3 plane. Two molecules of HC≡CZ react to afford the Pt3 complex with che...

Zusammenfassung:A new triangular triplatinum(0) complex with bridging diphenylgermylene ligands, [{Pt(PMe3)}3(μ-GePh2)3], undergoes insertion of ZC≡CZ (Z = COOMe) into a Pt-Ge bond. The product contains a μ3-η(2)(∥)-CZ=CZ-GePh2 ligand on the Pt3 plane. Two molecules of HC≡CZ react to afford the Pt3 complex with chelating C, Ge- and Ge, Ge-ligands.
