Abstract
Abstract Hexa-alkylphosphorus triamides and trifluoromethyl bromide react to give trifluoromethyltris(dialkylamino)phosphonium bromides which were used for the trifluoromethylation of benzaldehyde and copper(I) iodide in the presence of fluoride anions with different counterions; tris(diethylamino)difluorophosphorane proved to be a masked fluoride anion donor. The structures of [CF3P(NMe2)3]+Br− and [CF3P(NEt2)3]+Br− have been determined by single-crystal X-ray investigations and shown to exhibit a distorted tetrahedral bond configuration with a rather long (F3)CP bond of 1.866(9) or 1.896(6) A, respectively.
