Trifluoromethylation and pentafluoroethylation of terpenoid carbonyl compounds used in perfumery
摘要:
The reaction of trifluoromethyltrimethylsilane with a variety of terpenoid carbonyl compounds and other carbonyl compounds used in perfumery gave the corresponding trifiuoromethylated derivatives. Pentafluoroethylated compounds were similarly obtained from the reaction of pentafluoroethyltrimethylsilane with various substrates. (-)-2-Trifluoro-1-furyl ethanol has been obtained with high optical purity by enzymatic hydrolysis of 2-trifluoro-1-furyl ethyl acetate.

A room temperature method for the conversion of perfluoroalkyl iodides to α-perfluoroalkyl carbinols under Pd or Ni catalysis is reported. The use of trifluoromethyl bromide provides an economical procedure for trifluoromethyl substituted carbinols.
