Treatment of 1,3-diaryltriazene 1-oxides with
oxalyl chloride in dry toluene at room temperature gives only
solid arenediazonium chlorides; however, treatment with acetyl
and benzoyl chlorides does not afford the corresponding diazonium
chlorides.
Photolysis of the 1,3-dipolar unsymmetrical 1,3-triazene 1-oxides in aromatic and nonaromatic solvents led to their decomposition. 2-Hydroxyazobenzene, mono- and disubstituted biaryls were produced.
