Cleavage of halogen(s) from fluoro:halo cpds.

摘要

The cleavage of 1C fluoro-halo cpds. of formula CFaHalbHc (I) comprises reacting in a condensed phase with hydrogen in the presence of a supported precious metal catalyst (II); Hal = Cl and/or Br; a = 1, 2 or 3; b = 1, 2, or 3; c = 0, 1 or 2; and a + b + c = 4.
