Condensation of diaminomaleonitrile with PCl3, ME2NPCl2< (Me2N)2PCl, (Me2N)3P or (Et2N)3P yields the 4,5-dicyano 1,3,2-diazaphosphole ring. In a slower reaction the two cyano groups by adding Me2NH or Et2NH form a second fivemembered ring to give 1,3,5,2-triazaphosphapentalenes.
二氨基马来腈与PCl 3,ME 2 NPCl 2 <(Me 2 N)2 PCl,(Me 2 N)3 P或(Et 2 N)3 P的缩合产生4,5-二氰基1,3,2-二氮杂磷腈环。在较慢的反应中,通过添加Me 2 NH或Et 2 NH ,两个氰基形成第二个五元环,得到1,3,5,2-三氮杂磷戊烯。
