HCFC-123 (2,2-dichloro-1,1,1-trifluoroethane) reacted with zinc and aldehydes to afford predominantly either 1-substituted 2-chloro-3,3-difluoro-2-propen-1-ols or 1-substituted 2,2-dichloro-3,3,3-trifluoro-1-propanols. The reactions proceeded via 1,1-dichloro-2,2,2-trifluoroethylzinc chloride as an organozinc intermediate.
