HALOMETHYL DERIVATIVES OF SILICON, GERMANIUM, AND TIN BY THE DIAZOMETHANE METHOD 

Submitted by Dietmar Seyperth and Eugene G. RocHowf Checked by Julian B. Honeycutt, Jr.,J and Robert C. Bryan j  

The reaction of the appropriate halides with diazomethane is an elegant laboratory-scale method for the synthesis of halomethyl derivatives of silicon, germanium, tin, and lead.1-4 However, good yields are obtained only with the following types  

Low yields are obtained with halides of the following types, and a copper catalyst is necessary  

The synthesis of chloromethyldichlorosilane, chlorometh-ylgermanium trichloride, and chloromethyldimethyltin chloride are described below as examples of the general procedure. Copper was included in the silicon and germanium runs to further improve the reaction, but it is not necessary with the halides employed herein.
