Thermal decomposition of 2-azidosulphonylbenzophenones gives the 7-membered cyclisation products in addition to products in which nitrogen is bound to the ortho-position originally bearing the carbonyl group; ring chain tautomerism of the sulphonyl azides with 3-aryl-3-azidobenzo[d][2,1]oxathioles followed by decomposition of the latter and 1,2-aryl shifts is proposed to explain formation of the rearranged
除了氮与原始带有羰基的邻位键合的产物外,2-叠氮磺酰基二苯甲酮的热分解还产生了7元环化产物。提出了磺酰叠氮与3-芳基-3-叠氮基苯并[ d ] [2,1]草硫醇的环链互变异构,然后分解后者和1,2-芳基移位的方法,以解释重排产物的形成。
