Nucleophilic fluorine substitution reaction of α-carbonyl benzyl bromide, phenylthiofluoroalkyl bromide, and 2-bromo-2-phenoxyacetonitrile

Abstract

We herein describe a new method for nucleophilic fluorine substitution of alkylbromides using Et₃N·3HF. The process is characterized by a broad substrate scope, good functional-group compatibility, and mild conditions and provides a variety of alkylfluorides including tertiary alkylfluorides that are versatile and structurally attractive.
