of iodomethylzinc iodide with trimethylchlorogermane gave in low yield both Me3GeCH2I and Me3GeCH2GeMe3. These compounds were obtained in much better yield when ICH2ZnI was allowed to react with germanium tetrachloride and the reaction product was methylated with MeMgBr. The reaction of iodomethyl-tin compounds with silver chloride and bromine in acetonitrile served well in the preparation of Me3SnCH2Cl
Me 3 SnCH 2 I,Me 3 SnCH 2 Br,Me 2 Sn(CH 2 I)2,Me 2 Sn( CH 2 Br)2,Me 2 PhSnCH 2 I,Ph 3 SnCH 2 I,Sn(CH 2 I)4,Ph 3 PbCH 2 I,Hg(CH 2 I)2和Hg(CH 2 Br)2。在大多数情况下,产品的产量非常好。碘代碘化锌锌与三甲基氯锗烷的反应均产生了低收率的Me 3 GeCH 2 I和Me 3 GeCH 2 GeMe 3。当使ICH 2 ZnI与四氯化锗反应并将反应产物用MeMgBr甲基化时,这些化合物的收率要好得多。碘甲基锡化合物与氯化银和溴在乙腈中的反应对于制备Me 3 SnCH 2 Cl,Me 3 SnCH 2 Br,Me 2 Sn(CH 2 Cl)2,Me2 Sn(CH 2 Br)2和Me 2 PhSnCH 2 Cl。
