Products of the reaction of 2-[(hydroxyimino)methyl]-1,3-dimethylimidazolium iodide with diethyl 4-nitrophenyl phosphate in alkaline medium have been identified by electronic spectroscopy, one-(1H, 31P, 13C) and two-dimensional (1H–1H COSY, 1H–31P HMBC) NMR techniques, and NMR titration. 2-[(Hydroxyimino)-methyl]-1,3-dimethylimidazolium iodide has been found to act as nucleophile which is likely to
通过电子光谱鉴定了2-[((羟基亚氨基)甲基] -1,3-碘化咪唑鎓碘化物与4-乙基硝基苯基磷酸二乙酯在碱性介质中的反应产物,一种-(1 H,31 P,13 C)和两种维(1 H– 1 H COSY,1 H– 31P HMBC)NMR技术和NMR滴定。已经发现2-[(羟基亚氨基)-甲基] -1,3-二甲基咪唑碘化物起亲核试剂的作用,它很可能被转化成2-氰基-1,3-二甲基咪唑鎓。其他产物是4-硝基苯酚和磷酸二乙酯磷酸氢盐。已经排除了其他反应途径,例如2-((羟基亚氨基)甲基] -1,3-二甲基咪唑碘化物对磷酸二乙基4-硝基苯基酯水解的亲核催化和形成稳定的磷酸化产物。
