Two different reaction pathways are given from an alkyl halide to the homologous tert-butyl vinyl ether, both of them involving lithiated tert-butoxymethyl phenyl sulfone [tert-butoxy(phenylsulfonyl)methyllithium]. This new synthetic reagent is alkylated and the resulting sulfone is exposed to base-promoted elimination in the first route. The second route involves the coupling of this organometallic species with the lithium derivative of the phenyl alkyl sulfone (1-phenylsulfonylalkyllithium) corresponding to the halide, and provides a new example of reaction between two carbenoids, one of them acting as an electrophile.
