1-(m-Nitrophenylsulfonyl)- and 1-(p-nitrophenylsulfonyl)-1,3-butadienes in aqueous acetone in the presence of HCl and copper(I) or copper(II) chloride react with 1-aryl-3,3-dimethyl-1-triaenes to form 1-(m-nitrophenylsulfonyl)- and 1-(p-nitrophenylsulfonyl)-4-aryl-3-chloro-1-butenes, respectively. 1-(o-Nitro-phenylsulfonyl)-1,3-butadiene fails to react in similar conditions.

The reactions of 1-aryl-2-bromodiazene 1-oxides with HCl in nonaqueous media give aryldiazonium chlorides, while 1,3,3-substituted triazenes-1 are formed in the reactions with secondary amines. Using 2-15N} label, it was shown that the aryl group does not migrate in these reactions.

1,3-Butadiene and 2-methyl-1,3-butadiene react with 1,3-diphenyltriazene, 1,3-di-p-tolyltriazene, and 1-aryl-3,3-dimethyl-1-triazenes in a sulfur(IV) oxide-saturated water-acetic acid-acetone solution containing NaCl or hydrochloric acid, and catalytic amounts of copper(I) chloride to form 1,4-arylsulfonyl-chlorination products.

1-(p-Chlorophenylsulfonyl)- and 1-(p-bromophenylsulfonyl)-1,3-butadienes in aqueous acetone solutions in the presence of cuprous chloride or cupric chloride react with aryldiazonium chlorides and 1-aryl-3,3-dimethyl-1-triazenes to form 1-(p-chlorophenylsulphonyl)- and 1-(p-bromophenylsulfonyl)-4-aryl-3-chloro-1-butenes, respectively.
