Aryl radicals are produced from both ends of the hexazadienes 1 and 2 and from the tetrazene 3, either thermally or photolytically. They attack aromatic compounds in the nucleus, the yield of biaryl being in the range 40–70%, though it can be made nearly quantitative by using m-dinitrobenzene as an additive. The aryl radicals also oxidize 2-propanol to acetone, the reduction products being the halogenobenzene and 1,2-diacetylhydrazine.Photolysis of 1 goes mainly by way of the tetrazene 3, and this may also be a significant pathway in the thermal reaction. Azodiacetyl is an intermediate in the thermal reaction of 1 with 2-propanol and may be generally so in all its reactions.Radical induced decomposition is believed to be important in the reactions of 1, 2, and 3, and it is probably responsible for the formation of 1-acetyl-1-arylhydrazines, routinely produced in yields of up to 25%.
芳基自由基可以通过热力或光解产生自六氮烯1和2的两端以及四氮烯3。它们攻击芳香化合物的核,生成的双芳基产率在40-70%范围内,但通过使用m-二硝基苯作为添加剂几乎可以达到定量。芳基自由基还可以将异丙醇氧化为丙酮,还原产物为卤代苯和1,2-二乙酰肼。光解1主要经过四氮烯3进行,这在热反应中也可能是一个重要途径。三氮乙酰基是1与异丙醇热反应的中间体,可能在所有反应中普遍存在。自由基诱导分解被认为在1、2和3的反应中很重要,可能是产生1-乙酰基-1-芳基肼的原因,通常产率高达25%。
