Reaction of sodium benzenesulfinate with 1,2-di(4-chloro-benzenesulfonyl)-2-hexen-4-yne affords not only the regiospecific addition of the nucleophile at Carbon-5 but also effects concomitant vinylic and allylic displacements at Carbons-1 and 2

The hexa-2,4-diene derivative (2), obtained from 1,6-di(phenylsulphonyl)hexa-2,4-diyne (1), is shown to undergo simultaneous Isomerization at both double bonds, through an elimination-addition pathway.

Base-catalyzed addition of arene thiols to 1,4-disubstituted-2-butynes (1 and 2) afford the β,γ-unsaturated sulfones (8E and 8Z). In addition to the regiospecificity observed, the vinyl sulfides are formed with a high degree of stereoselectivity. P
