Methanol into hydrocarbon conversion. A mechanistic study: an oxygen ylide intermediate
Abstract
Methyl ethyl ether is formed by treating trimethyloxonium hexachloroantimonate with the strongly hindered base,2,2,6,6-tetramethylpiperidyl-lithium; this reaction is attributed to the formation of an oxygen ylide followed by a stevens-type rearrangement or intermolecular methylation.
