- NUCLEOPHILIC REACTIONS AT A VINYL CENTER. XIII. REACTION OF β,β-DIBROMOVINYL PHENYL SULFONE WITH SODIUM IODIDE AND THE REACTIVITY OF β,β-DIIODOVINYL PHENYL SULFONE
-
β-Bromo-β-iodovinyl phenyl sulfone and β,β-diiodovinyl phenyl sulfone were obtained by the reaction of β,β-dibromovinyl phenyl sulfone with sodium iodide in acetone.The reactivity of β,β-diiodovinyl phenyl sulfone in reactions with sodium methoxide and thiophenolates was studied.A comparison was made of the relative reactivities of the various β,β-dihalogenovinyl sulfones (Hlg = Cl, Br, I) in nucleophilic vinylic substitution within the scope of the elimination-addition and direct substitution mechanisms.
