M. Nasim et al., SYNTHESIS OF O-GERMATRANYL AND C-GERMATRANYL DERIVATIVES OF THE ESTERS OF ACETIC-ACID, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 35(12), 1996, pp. 1257-1259
The O- and C-germatranyl derivatives of the esters of acetic acid have
been obtained by the action of alkoxygermatranes with bis(trifluorome
thyl)ketene and diphenylketene. The C-isomers have also been obtained
in high yields by the action of methyl (trichlorogermyl) acetate and m
ethyl (trichlorogermyl)(diphenyl)acetate with tris(2-triethylstannoxye
thyl)amine.
