PREPARATION OF ALKYL-ARYL ETHERS AND THIOETHERS

Article abstract of DOI:10.1016/S0040-4020(01)81713-0

A method, which involves no molecular rearrangement, and which is also stereospecific, for the preparation of alkyl-aryl ethers and thioethers is described.Stable alkoxyphosphonium salts, R-O-P(1+)(NMe2)3 PF6(1-), have been prepared and treated with phenols and thiophenols, under basic conditions, to yield the corresponding alkyl-aryl ethers and thioethers respectively.
