Abstract
Process for preparing halogenated hydrocarbons, comprising at least 3 carbon atoms, by catalytic telomerization between a haloalkane and an olefin in the presence of an amine with a high boiling point as co-catalyst. 1,1,1,3,3-Pentachloropropane and 1,1,1,3,3-pentachlorobutane are thus prepared under mild conditions in good yield and the catalyst/co-catalyst system can be easily separated by distillation and recycled.
