In the present work, dehydrogenation of 2-substituted imidazolines with sodium periodate in the presence of tetraphenylporphyrinatomanganese(III) chloride, [Mn(TPP)Cl], is reported. A wide variety of 2-imidazolines efficiently converted to their corresponding imidazoles by [Mn(TPP)Cl]/NaIO(4) catalytic system at room temperature in 1:2, CH(3)CN/H(2)O mixture. The effect of reaction parameters such as kind of solvent and catalyst amount was also investigated.
在本工作中，报道了在四苯基卟啉锰(III)氯化物[Mn(TPP)Cl]的存在下，用高碘酸钠使 2-取代的咪唑啉脱氢。在室温下，在 1:2 的 CH(3)CN/H(2)O 混合溶剂中，通过[Mn(TPP)Cl]/NaIO(4)催化体系，多种 2-咪唑啉高效地转化为相应的咪唑。还研究了反应参数如溶剂种类和催化剂用量的影响。
