A new strategy for the transformation of terminal alkynes to branched allylic sulfones was developed. Using a Rh(I)/DPEphos/benzoic acid catalyst system, terminal alkynes react with sulfonyl hydrazides to produce branched allylic sulfones with good to exc
Dramatic Solvent Effects and Stereospecificity in Allylic Sulphinate-Sulphone Rearrangements

Dramatic solvent effects were observed in the thermolysis of allyl sulphinates; heating of chiral trans- and cis-allyl sulphinates (S)-(-)-(1a - g) in N,N-dimethylformamide at 90 - 120 deg C provided chiral sulphones (2a - d) in good yields with very high stereospecificity.
