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.
Preparation of Nitriles from Primary Alcohols by a New Type of Oxidation-reduction Condensation Using 2,6-Dimethyl-1,4-benzoquinone and Diethyl Cyanophosphonate
Cyanation of alkoxydiphenylphosphines, in situ prepared from nBuLi and various primary alcohols, with 2,6-dimethyl-1,4-benzoquinone (DMBQ) and diethyl cyanophosphonate provided the corresponding nitriles in high yields.
