1,2,4-Oxadiazole-4-oxides undergo clean thermal cleavage in refluxing chlorobenzene or xylene to nitriles and nitrosocarbonyl intermediates, which are either trapped with suitable olefins to afford ene adducts or dimerize and rearrange to anhydrides.
1,2,4-氧杂二唑-4-氧化物在氯苯或二甲苯回流为腈和亚硝基羰基中间体的过程中经历干净的热裂解,这些中间体或腈中间体被适当的烯烃捕集,得到烯属加合物或二聚并重排为酸酐。
