Reaction of arendiazonium salts and SO2with α-nitroolefins
In reaction of β-nitrostyrene and 2-(2-nitrovinyl)furan with arenediazonium chlorides and SO2 in the presence of copper(II) chloride products were obtained resulting from addition of arylsulfonyl group and a hydrogen atom across the C=C bond: 2-nitro-1-phenylethylsulfonylarenes and 2-(1-arylsulfonyl-2-nitroethyl)furans respectively. An anion-radical mechanism of the reaction was suggested.

KINETIC STUDIES ON REACTION OF SULFINIC ACIDS WITH CONJUGATED ALKENES: I. KINETICS OF THE ADDITION OF ARENESULFINIC ACIDS TO β-NITROSTYRENE
Addition of unsubstituted and substituted benzenesulfinic acids to β-nitrostyrene has been studied kinetically by means of ultraviolet spectrophotometry.The reaction follows the second-order kinetics: ν=k. .The dependence of rate constants on the temperature and influence of p-substituents on the kinetic parameters have been investigated.The activating energy and the enthalpy of activation are calculated in the temperature range 288-308 K. Key words: Sulfinic acids; β-nitrostyrene; reaction order; rate constants; activating energy; enthalpy of activation.
