Reaction of trifluoroacetic acid with chlorodiphenylphosphine
Abstract
The reaction of trifluoroacetic acid with chlorodiphenylphosphine at 160–170° gives 1-diphenylphosphinyl-2,2,2-trifluoroethyl diphenylphosphinate together with small amounts of 1-hydroxy-2,2,2-trifluoroethyldiphenyl-phosphine oxide and diphenyl-2,2,2-trifluoroethylphosphine oxide.
