Versuchsvorschrift

A mixture of 2-bromoethyl phenyl ether (20.0 g), triphenylphosphine (26.2 g) and phenol (200 g) was heated at 90° C. with stirring for 48 hours. The mixture was cooled to approximately 40° C. and added to ether (1500 ml). The ether was decanted off and the residual oil was triturated with ether until a solid was obtained. The solid was collected by filtration to give (2-phenoxyethyl)triphenylphosphonium bromide.
