PCT No. PCT/US96/12548 Sec. 371 Date Jan. 28, 1998 Sec. 102(e) Date Jan. 28, 1998 PCT Filed Jul. 31, 1996 PCT Pub. No. WO97/05090 PCT Pub. Date Feb. 13, 1997A liquid phase process is disclosed for producing halogenated alkane adducts of the formula: CAR1R2CBR3R4 (where, A, B, R1, R2, R3 and R4 are defined in the specification) which involves contacting a corresponding halogenated alkane, AB, with a corresponding olefin, CR1R2=CR3R4, in the presence of a catalyst system containing (i) at least one catalyst selected from monovalent and divalent copper, and (ii) a promoter selected from aromatic or aliphatic hetercyclic compounds which contain at least one carbon-nitrogen double bond in the heterocyclic ring. When hydrochlorofluorocarbons are formed, hydrofluorocarbons may be formed therefrom by reacting the hydrochlorofluorocarbons with HF.
