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.
WebThe analysis of the electronic structure of the neutral metal germylyne complexes Ia−Id and the metallogermylenes IIa−IId shows that the former compounds have about the same degree of electrostatic and covalent bonding, while the relative strength of the covalent contributions in the latter molecules is lower (41−42%) than the electrostatic … WebA chromium germylyne (or germylidyne) complex having a Cr Ge triple bond, [Cp*(OC)2Cr GeTsi] (1) (Tsi = C(SiMe3)3), was directly synthesized by the photochemical reaction of a methyl chromium complex [Cp*Cr(CO)3Me] and a trihydrogermane (TsiGeH3). Detailed monitoring the reaction by NMR revealed the initial formation of hydrido (hydrogermylene ...
