compounds were characterized by means of spectroscopy and the formation of carbenes upon thermolysis of a few was demonstrated by means of interception with tert-butyl alcohol. The carbenes fragmented to form methoxycarbonyl and iminyl radicals.Key words: 2,2-dioxyoxadiazoline, methoxy(oximino)carbene, oxadiazole, radical pair, rearrangement.
通过将 2-乙酰氧基-2-甲氧基-Δ3-1,3,4-恶二唑啉的乙酰氧基与肟基交换,合成了十种新的甲氧基(肟基)卡宾的恶二唑啉来源。新化合物通过光谱学表征,并且通过用叔丁醇拦截证明了在一些热解时形成卡宾。卡宾断裂形成甲氧基羰基和亚胺基。关键词:2,2-二氧恶二唑啉,甲氧基(肟基)卡宾,恶二唑,自由基对,重排。
