by two new methods: (a) the reaction of N-aryl-SS-dimethylsulphimides with nitrile oxides, and (b) the oxidation of N-arylamidoximes. Both reactions are shown to involve the intermediacy of N-aryl-C-nitroso-imines, which can be reversibly intercepted in a Diels-Alder reaction with thebaine. Earlier publications on the synthesis of 1,2,4-benzoxadiazines have been re-assessed, and some of the structures
1,2,4- Benzoxadiazines(1)已经制备由两个新方法:(一)的反应Ñ -芳基- SS -dimethylsulphimides与氧化腈,和(b)的氧化Ñ -arylamidoximes。两个反应均表明涉及的中间性Ñ -芳基- C ^亚硝基亚胺,它可与一个蒂巴因Diels-Alder反应被可逆地截获。对1,2,4-苯并恶二嗪合成的早期出版物进行了重新评估,并对先前工作人员提出的一些结构进行了修订。
