A variety of quaternary ammonium salts derived from 2-aryl-3-(N,N-dimethylamino)-1-propenes have been converted to the corresponding alkyl and fluoroalkyl ethers by displacement of the ammonium group.This procedure represents an efficient means for the construction of 2-aryl substituted allylic ethers.
Effect of the α-Trifluoromethyl Moiety on the Solvolysis of Allylic Sulfonates

A series of allylic sulfonates bearing aryl substituents on the 2-position and/or trifluoromethyl groups on the 1- and/or 3-positions has been studied under solvolytic conditions in 2,2,2-trifluoroethanol.Nonarylated 1,3-di(trifluoromethyl)-substituted allylic sulfonates did not solvolyze in a conventional manner but instead gave products diagnostic of a complex isomerization-cleavage process.Mono(trifluoromethyl)-substituted allylic sulfonates solvolyzed by normal paths to give kH/kCF3 ratios of 2E6 and 4E4 for the substitution at the 1- and 3-positions, respectively.No evidence for 1,3-? interactions was discerned.
