1974年Jacqueline和Pierre制得2-[(甲硫基)甲基]-1 H苯并咪唑并测定了其第一级电离平衡常数(K_1)。有关此化合物与铜离子的络合物尚未见报道。我们测定了此化合物(以下简称MTMBI)的第一和第二电离平衡常数及热力学常数,研究了它与铜(Ⅱ)离子所形成的络合物,测定了逐级积累稳定常数。
In 1974, Jacqueline and Pierre prepared 2 - [(methylthio) methyl] -1H benzimidazole and determined the first order ionization equilibrium constant (K_1). Complexes of this compound with copper have not been reported yet. We determined the first and second ionization equilibrium constants and thermodynamic constants of this compound (hereinafter referred to as MTMBI), studied the complex formed with copper (II) ions and determined the accumulation stability constants stepwise.
