been achieved. The reaction occurs by S-directed C–H activation at the ortho position of the aryl ring, promoted by ruthenium, migratory insertion of the alkyne, 1,2-thio-Wittig rearrangement of the tert-butyl group and reductive elimination by C–S coupling between the resulting anionic sulfide and the vinylic carbon.
