The transformation of hydroxyl group in benzyl or allyl alcohols to trifluoromethyl was achieved via the reaction of the corresponding alkyloxydiphenylphosphine and CuCF3, generated in situ from methyl fluorosulfonyldifluoroacetate and CuI, under mild conditions. A plausible mechanism was proposed on the basis of experimental results.

[reaction: see text] We describe a new, straightforward, and easy-to-handle method for achieving an unprecedented trimethylsilyl halide-catalyzed Michaelis-Arbuzov-like rearrangement. This rearrangement occurs at temperatures from room temperature to 80 degrees C and does not require addition of any alkyl halide. The scope and limitations of this new reaction are explored, as well as its mechanism
