compounds in the presence of copper species, such as copper(I) chloride, copper(II) chloride or metallic copper, to form polyhalo compounds containing an allyl group. Other allylsilane derivatives than allyltrimethylsilane were also subjected to a reaction with carbontetrachloride. 3-Chloro- or 3-bromo-3-trimethylsilyl-1-propene gave 4,4,4-trichloro-1-trimethylsilyl-1-butene.

The free radical addition of carbon tetrachloride to 2,2-dichlorobut-3-enonitriles gives both normal and rearranged addition products, namely hexachlorohexanonitriles and 3-cyanohexachloropentanes, respectively. The latter products are believed to be formed by migration of the cyano-group in the intermediate 3-cyanopropylradical formed on addition of a trichloromethyl radical to the substrate. The
