Treatment of the lithium salt of allyl phenyl sulphone (1) with a variety of alkyl halides affords exclusively α-alkylated products (2a-d). which are easily isomerized to (E)-αβ-unsaturated phenyl sulphones (4a-d) with catalytic amounts of t-butoxide. A new, simple method of reductive cleavage of the carbon-sulphur bonds of compounds (2)-(4) with potassium-graphite (C8K) is described, providing a general route to alk-2-enes [(5) and (6)] in satisfactory yields.
