Reaction of Arendiazonium Salts and SO2with α-Nitroolefins
摘要:
In reaction of beta-nitrostyrene and 2-(2-nitrovinyl)furan with arenediazonium chlorides and SO2 in the presence of copper(H) 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-aryisulfonyl-2-nitroethyl)furans respectively. An anion-radical mechanism of the reaction was suggested.
