New Reagents, XXXI. Synthesis of (Iodomethyl)‐and (Diiodomethyl)element Compounds of the Elements Si, Ge, Sn, Pb Via LiCH 2 Hal or LiCHHal 2 (Hal = I, Br), respectively, the monohalides Ph 3 ElCH 2 I (El = Si, Ge, Pb) and Ph 3 GeCH 2 Br have been obtained (49–74%) as well as the dihalides Ph 3 ElCHI 2 (El = Si, Ge, Sn; 49–69%), Ph 3 PbCHI 2 (9%), and Ph 3 GeCHBr 2 (78%). These compounds are favourable starting materials for corresponding monolithium compounds. Some of them have found synthetic applications.
