The reactions of the PMe3 adduct of the silylated germylene [(Me3Si)3Si]2Ge: with GeCl2·dioxane were found to yield 1,1-migratory insertion products of GeCl2 into one or two Ge–Si bonds. In a related reaction, a germylene was inserted with tris(trimethylsilyl)silyl and vinyl substituents into a Ge–Cl bond of GeCl2. This was followed by intramolecular trimethylsilyl chloride elimination to another cyclic germylene PMe3 adduct. The reaction of the GeCl2 mono-insertion product (Me3Si)3SiGe:GeCl2Si(SiMe3)3 with Me3SiC≡CH gave a mixture of alkyne mono- and diinsertion products. While the reaction of a divinylgermylene with GeCl2·dioxane only results in the exchange of the dioxane of GeCl2 against the divinylgermylene as base, the reaction of [(Me3Si)3Si]2Ge: with one GeCl2·dioxane and three phenylacetylenes gives a trivinylated germane with a chlorogermylene attached to one of the vinyl units.

The CO migratory insertion into M–O and M–C bonds of the new model (PMe3)2M(η2 – CH2CH2O) ( M = Ni , Pd and Pt ) (model (d)) proposed in this work has been studied with the aid of density functional theory (DFT) calculations. It is found (1) when M = Ni , CO migratory insertion into Ni–C is thermodynamically and kinetically favored, and (2) when M = Pd and Pt , the insertion into M–O bond via a one-step process is preferred. Further investigation on CO migratory insertion using Pt(PMe3)2(C7H10O) (R′-Pt) derived from the experimental compound Pt(PEt3)2(C7H10O) gives the same conclusions as model (d) with M = Pt . Results obtained from the reaction of model (d) ( M = Pt ) with CO are consistent with the experimental observation that CO prefers to insert into Pt–O bond of Pt(PEt3)2(C7H10O) .
