Irradiation for permethyloligogermanes, Me(Me2Ge)nMe (n=2-5), in CCl4-CH3CN in the presence of 9,10-dicyanoanthracene (DCA) afforded the corresponding chlorogermanes and hexachloroethane. Fluorescence of DCA was quenched by the oligogermane with a diffusion-controlled rate. A mechanism of free-radical chlorination involving oligogermane cation radicals and a DCA anion radical is proposed for the germanium-germanium cleavage.

The synthesis, reactivity, and characterization of the digermylplatinum(II) linear complexes (ClMe2Ge)2Pt(PPh3)2 (1) and (ClMe2Ge)2Pt(diphos) (2) and cyclic complexes (diphos)PtGe-(Me2)EGeMe2 [E = S (3), -NPh (4), (η5-C5H4)Fe(η5-C 5H4) (5), O (6)] are reported. The chemistry of 2-6 is illustrated through their reactions with phenylacetylene and N-methyltriazolinedione. Complexes 3 and 6 give double germylation of these unsaturated systems, while 2, by reaction with triazolinedione, gives the monogermylated complex Me2-(Cl)GePt(Cl)diphos and the dimer of the germylated heterocycle Me2GeNC(O)N(Me)C(O)N.

Photochemical reactions of vinyl-, styryl- and benzyl-substituted digermanes by chemical trapping experiments.Photolysis of vinylpentamethyldigermane afforded 1-trimethyl-2-(pentamethyldigermyl)ethane as a major product, and styrylpentamethyldigermanes gave mainly styryltrimethylgermane.On the other hand, photolysis of benzyl-substituted digermanes (benzylpentamethyldigermane and 1,2-dibenzyltetramethyldigermane) gave hydrogermanes and hydrodigermanes as main products, respectively.These products were derived from germyl radicals generated by photoinduced homolysis of the germanium-germanium bond.In carbon tetra chloride (CCl4), these germyl radicals were converted to the corresponding chlorogermanes by abstraction of a chlorine atom.Germylene species were also to be evolved from such photolyses.

The photolysis and thermolysis of 2,3-digerma-1,4-dithianes, 2,3,5-trigerma-1,4-dithiolanes and tetragerma-1,4-dithianes have been studied. 2,2,3,3-Tetramethyl-2,3-digerma-1,4-dithiane (I) decomposes slowly at room temperature by α-elimination to yield di
