The mechanism of nucleophilic substitution of the chlorine atoms in dichlorovinyl aryl sulfones by sodium thiophenolates in methanol was investigated.A mechanism of "direct" vinyl substitution is confirmed by the absence of isotope exchange in CH3OD.The i
NUCLEOPHILIC REACTIONS AT VINYL CENTER. IV. REACTION OF β, β-DICHLOROVINYL SULFONES WITH SODIUM THIOPHENOLATES

The kinetics of the reaction of β,β-dichlorovinyl sulfones with substituted sodium thiophenolates in methanol at 0 - 50 deg C were investigated.The reaction occurs with substitution of both chlorine atoms of thioaryl group, and the ratio of the rate constants for the substitution of the first and second chlorine atoms depends largely on the substituent in the nucleophile and depends little on the substituent in the substrate.A one-factorial and crossed analysis of the reactivity was undertaken.
