The novel light-induced reaction of diazometharie with carbon tetrachloride gives 1, 3- dichloro-2, 2-bis-(chloromethyl)-propane and nitrogen. Analogous reactions with bromotrichloromethane and chloroform yield 1, 3-dichloro-2-bromomethyl-2- chloromethylpropane and 1, 3-dichloro-2-chloromethyl-2-methylpropane, respectively. a- Haloesters undergo similar reactions: methyl trichloroacetate to give methyl tris-( ...
