The new [5.7.4]tricyclic ring system 3 is synthesized in a one-pot reaction from bis(iminophosphorane)1 and two equivalents of aryl isocyanate; compound 1 also reacts with one equivalent of isocyanate to give the bicyclic [1,3]diazepine 6; the crystal structure of compounds 3 and 6 are determined.
新的[5.7.4]三环系统 3 是由双(亚氨基磷烷)1 和两个当量的芳基异氰酸酯通过一次反应合成的;化合物 1 还与一个当量的异氰酸酯反应生成了双环[1,3]二氮杂卓 6;化合物 3 和 6 的晶体结构已经确定。
