An alternative approach to HCFC's is the chlorination of fluorocarbons such as CH3CF3 (HFC-143a). For example, McBee (Industrial and Engineering Chemistry, Vol. 39, pp. 409-412 (1947)) reported that vapor phase chlorination of HFC-143a afforded a mixture of HCFC-133a, HCFC-132b, CHCl2CF3 (HCFC-123), and the fully chlorinated CF3CCl3 (CFC-113a). McBee also reported the chlorination of CH3CClF2 (HCFC-142b) to give HCFC-132b, HCFC-122, and the fully chlorinated CClF2CCl3 (CFC-112a). Again, using this technique --CH2Cl and --CHCl2 groups dominate the attainable substitution pattern.
