Anti-Markownikoff 1,2-hydrosulphonylation of 1,3-dienes viaπ-allylpalladium complexes

Abstract
The reaction of palladium(II) chloride with 1,3-dienes and sodium alkanesulphinates in acetic acid produces di-µ-chloro-bis(1-syn-alkylsulphonylmethyl-π-allyl)dipalladium(II) complexes, which on treatment with dimethylglyoxime in methanol are degradated selectively to γδ-unsaturated sulphone.
