Synthesis of trifluoromethylated compounds from alcohols via alkoxydiphenylphosphines

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.

Selective synthesis of isocyanides from secondary alcohols by a new type of oxidation-reduction condensation

Selective synthesis of isocyanides from secondary alcohols via alkyl diphenylphosphinites is established by a new type of oxidation-reduction condensation in controlling the ambident reactivity of cyanide anion. In the presence of ZnO, isocyanides are obtained exclusively in moderate to high yields. Copyright

SYNTHESE CHIRALER PHOSPHINOXIDE UND PHOSPHINE DURCH MICHAELIS-ARBUZOV-UMLAGERUNG

Several phosphinites and phosphites, derived from chiral alcohols, were synthesized.The phosphinites were subjected to a I2-catalyzed Michaelis-Arbuzov rearrangement.Phosphinites derived from primary alcohols give satisfactory yields of the corresponding phosphineoxides.Phosphinites synthesized from secondary alcohols also undergo the rearrangement but numerous byproducts appear in the reaction mixtures.Optical resolutions of chiral phosphineoxides by crystallization with optically active acids were not successful.The corresponding phosphines can easily be prepared by reduction of the oxides with trichlorosilane.
