The reaction between (Et3Ge)2Cd and TiCl4 in the presence of α,α'-bipyridyl afforded a compound with a Ge-Cd-Ti group.This compound was characterized by IR and ESR spectroscopy.Thermal decomposition of this compound at 130 and 160 deg C and its interaction with gaseous HCl were studied.A novel complex, (Et3Ge)2Cd*bpy, was obtained as a by-product of the reaction, and some its physicochemical characteristics were determined.Based on the experimental results, a scheme for the interaction of (Et3Ge)2Cd with TiCl4 has been suggested. - Key words: mixed organo-Cd, Ti compounds.
REDUCTION OF ALKOXYSILANES, HALO-SILANES AND -GERMANES WITH LITHIUM ALUMINIUM HYDRIDE UNDER PHASE-TRANSFER CONDITIONS
Gevorgyan, V. N.,Ignatovich, L. M.,Lukevics, E.
, p. C31 - C32 (1985)
In the presence of phase-transfer catalysts, silicon and germanium organohydrides were obtained in high yield by reduction of the corresponding halo and alkoxy derivatives with lithium aluminium hydride in the solid LiAlH4/hydrocarbon two-phase system.

A trigonal-bipyramidal Pt3Ge2 cluster was synthesized by the reaction of the zerovalent platinum complex [Pt(dppe)(η2- C2H4)] (dppe = 1,2-bis(diphenylphosphino)ethane) with the unsymmetrical digermane H3GeGeEt3 at a 3/2 molar ratio. The platinum centers formed a triangular plane bridged by two germylyne ligands, one of which maintained the Ge-Ge bond. To investigate the Pt 3Ge2 cluster formation process, the phenyl-substituted digermanes HPh2GeGeMe3 and H2PhGeGeR 3 (R = Me, Et), in which two hydrogen atoms and one hydrogen atoms of the reactive GeH3 moiety were replaced by the bulkier phenyl group(s) together with the substitution of the GeEt3 group by a GeMe3 group, respectively, were used to simplify the reaction system. They provided the digermylplatinum hydride [Pt(dppe)(H)(GePh 2GeMe3)] (2) and the bis(μ-germylene)diplatinum complexes [Pt2(dppe)2(μ-GeHPh)(μ-Ge(Ph)GeR 3)] (3, R = Me; 4, R = Et) in moderate yields, respectively. For 3 and 4, the first-formed digermylplatinum hydride I-1 underwent dissociation of one of the phosphorus donors followed by 1,2-germyl migration to give the corresponding bis(germyl)platinum complex I-2, as observed in the previously reported silicon system. On the one hand, the germyl migration did not take place in the case of 2, owing the Ge-Ge bond being less reactive than the Si-Si bond. Intermediates I-1 and I-2 coupled to each other to afford the germylene-bridged diplatinum complexes 3 and 4 accompanied by extrusion of H2 and R3GeH. In the case of H3GeGeEt 3, the corresponding bis(μ-germylene)diplatinum complex reacted with [Pt(dppe)(η2-C2H4)], resulting in the formation of the desired Pt3Ge2 cluster. The spiro-type Pt4Ge complex was obtained only by changing mole equivalents of [Pt(dppe)(η2-C2H4)], demonstrating the usefulness of the present method using H3GeGeEt3, which can readily regulate the molar ratio.
