Organic synthesis with sulfones no. XXXV. Iron catalysed condensation and hydrogenolysis of vinylic sulfones with Grignard reagents. A stereoselective synthesis of di- and trisubstituted olefins

Vinylic sulfones are readily available in the E or Z configuration.Condensation with primary Grignard reagents occurs stereospecifically in the presence of iron catalysts, leading to trisubstituted olefins.With secondary Grignards stereospecific hydrogenolysis to 1,2-disubstituted olefins is observed.

Selective alkylation of allyl phenyl sulphone. A novel synthesis of alk-2-enes

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.
