Abstract

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.
