by the reaction of (diphenylphosphoryl)methyl p-toluenesulfonate with alkynethiols, -selenols, or -tellurols at room temperature. The (diphenylphosphoryl)methyl phenylethynyl sulfides, selenides, or tellurides reacted with aldehydes and cyclic ketones to give the corresponding alkynyl vinyl sulfides, selenides, or tellurides, with preferential E-stereochemistry, in a Horner-Wittig-type reaction.
