Polynuclear germylmercury compounds are obtained from the reaction of organohydrogermanes PhnGeH4−n or digermanes Ph2nGe2H4−n (n = 1, 2) with dialkylmercury R2Hg. Di- or tri-mercurated geminal polygermates thus synthesized generally present a low stability and undergo thermal- or photo-decompositions leading to the corresponding monovalent (germynes), divalent (germylenes) or, trivalent (germanium
多有机环锗烷基汞化合物是从有机氢锗酸Ph n GeH 4- n或二锗烷基Ph 2 n Ge 2 H 4- n(n = 1,2)与二烷基汞R 2 Hg的反应中获得的。如此合成的二或三聚汞的双聚锗酸酯通常表现出较低的稳定性,并且会发生热分解或光分解,从而导致相应的单价(锗烷),二价(亚锗烷)或三价(锗中心自由基)物种以及中间双自由基可以认为是锗双键化合物的极限形式。这样的中间体已经在化学和光谱学上表征。

Synthesis and reactivity of 1,1,2,2-tetraphenyl 1,2-digermyldilithium
The new 1,1,2,2-tetraphenyl 1,2-digermyldilithium compound (2) is prepared in high yield by metallation of the corresponding aryldihydrodigermane (1) with t-BuLi in THF. It is characterized by C-13 NMR spectroscopy and by alkylation with methyl iodide. Some nucleophilic substitution reactions are reported: compound 2 reacts with MesCOCl to give a new digermyldiketone [Ph2(MesCO)Ge]2 (8). Its germylation reaction with several alkyl methoxygermanes or -digermanes constitute a convenient way for synthesizing cyclopolygermanes (3,4 or 6 rings). Its reaction with trans-Cl2Pt(PEt3)2 leads to a mixture of the expected cyclic complex 12 and its corresponding oxide 13.
