Abstract
Polyhalogenated hydrocarbons of general formula RR.sup.1 CH--CHX--CH.sub.2 CYZQ wherein R is hydrogen or lower alkyl, R.sup.1 is lower alkyl, X is Cl, Br or I, Y is F, Cl or Br, Z is Y or Q and Q is a group W(CF.sub.2).sub.m --in which W is hydrogen, F or Cl and m is 1 or 2, provided that X is always Br or I when at least one of Y and Z is Br, and a process for preparing these polyhalogenated hydrocarbons by reacting an alkyl-substituted butene with a polyhalogenated alkane having from 2 to 4 carbon atoms, in the presence of a catalyst.
