Reaction of the lithio-anion derived from dimethyl methanephosphonate with alkyl arenesulphinates gives directly lithiated dimethyl arenesulphinylmethanephosphonates. In situ reaction with aldehydes gives in high yield separable mixtures of E- and Z-vinylic sulphoxides in a convenient one-pot procedure.
