Some new phosphorus(V) hydrazides 1a–12a were synthesized and characterized by 1H, 13C, 31P NMR, IR spectroscopy and elemental analysis. Moreover, the interaction of Cu(M)2·nH2O with 1a, 3a and 7a gave 4,4′-bis(morpholine)diazene (1b). In fact, in these reactions, copper(II) ions acted as oxidizing agent. The results supported the proposed mechanism. The structures of compounds 1a, 1b and 1c were further
合成了一些新的磷酰肼1a - 12a,并通过1 H,13 C,31 P NMR,IR光谱和元素分析对其进行了表征。此外,Cu(M)2 · n H 2 O与1a,3a和7a的相互作用产生了4,4'-双(吗啉)二氮烯(1b)。实际上,在这些反应中,铜(II)离子充当氧化剂。结果支持了拟议的机制。化合物1a,1b和1c的结构通过X射线晶体学进一步确定。化合物筛选了1a – 12a的抗菌活性。另外,使用Ellman方法测量了1a,3a,7a,11a和12a的乙酰胆碱酯酶和丁酰胆碱酯酶抑制活性。有趣的是,与AChE相比,这些化合物是更有效的BChE抑制剂。同样,使用Lineweaver–Burk图,表明这些化合物是混合抑制剂。
