Diorganogermanium Dihalides

Unsubstituted symmetric organogermanium dihalides contain one organic moiety and one kind of halogen. The following scheme depicts synthetic methods for unsubstituted organogermanitmi dihalides listed in Table 51  

t By rxn. of Me Ge in the presence of cat. GaCl3 in a sealed tube with GeCU (1 1 to 1 5) at 235-2l -0 , in quant, yield (I856), with MeGeCU (1 2), in 9 % yield (I856). 

By rxn. of Me4Ge with AcCl and AICI3 (1 2 2) at r.t. in T07o yield (1T81). 

By rxn. of Ge with MeCl, effect of radio frequency field on formation (2 86). 

By-prod, in rxn. of MesGeCl with Cl at 100 , in daylight and under UV irradiation, in 10 and yield, resp. (2133)
