WebFeb 12, 2014 · In addition, two diastereomers can be formed from the reaction of a tungsten–germylyne complex with benzaldehyde. The interconversion of two diastereomers is involved in the consecutive decoordination of the C(O)Ph ligand, rotation of the germylene ligand, and recoordination of the C(O)Ph ligand to the germanium center. WebFollowing this procedure the analogous chromium and tungsten complexes featuring a triple bond with germanium were isolated.
