General description

p-Tolyl [2-(trimethylsilyl)ethynyl] sulfone is an aryl trimethylsilylethynyl sulfone. It can be synthesized from bis(trimethylsilyl)acetylene.

Application

p-Tolyl [2-(trimethylsilyl)ethynyl] sulfone (1-tosyl-2-(trimethylsilyl)acetylene) may be used as a reactant in the synthesis of Cp(OC)2M-C=CSiMe3 (M = Fe, Ru) by reacting with [Cp(OC)2M ]-Na+ and as a reagent in the photochemical alkynylation of unreactive C (sp3)–H bonds.
