same diaziridinone obtained previously from solution photolysis, but it also underwent a novel cleavage to MeNCO and, presumably, methyl azide. Iminotetrazolines () and () gave the corresponding carbodiimides () and (), and iminodiaziridines () and (); while the tetrazolinethiones () and () gave carbodiimides () and (), respectively. Photolysis of the vinyl substituted tetrazolinone () proceeded differently
六种1,4-二氢-5-四唑(四唑啉)衍生物已在12 K的Ar和N 2基质中进行了光解。对MeNCO和大概是叠氮化物的新裂解。亚氨基四唑啉()和()得到相应的碳二亚胺()和()以及亚氨基二氮丙啶()和();而四唑啉酮()和()分别得到碳二亚胺()和()。乙烯基取代的四唑啉酮的光解()在惰性环境温度溶液和低温基质中的处理方式有所不同。在前者中,咪唑酮()是唯一可分离的产物,而在后者中,二叠氮酮()的形成与另一种裂解反应竞争,从而得到异氰酸丁酯和叠氮化乙烯基。这些结果最好在中间双基的基础上解释,但是,矩阵ir无法直接检测到。光谱学。
