摘要：

A solid-liquid substitution reaction of (Mes)(3)SnCl with MX(Mes = mesityl: x = OCN, N-3, CN and SCN: M=Na or K) was carried out in the presence of one of three crown ethers (18-crown-6, 15-crown-5, and 12-crown-4) as well as in the absence of them, using n- hexane as a solvent at 25 degrees C. The reaction attained equilibrium in a shorter period in the presence of the crown ethers than in the absence of them, except the reaction with KCN. The extent of the substitution was dependent on X, but nearly independent on the kind of the three crown ethers.
