摘要

为了继续系统研究硫氰酸阴离子在乙腈中电化学氧化生成硫氰酸根的机理，我们通过实验（循环伏安法、电解法）和理论（数字模拟、量子化学计算）方法研究了质子供体对硫氰酸根生成和对硫氰酸根本身反应性的影响。在一系列不同强度的酸（乙酸、三氟乙酸和高氯酸）中，只有在强质子供体高氯酸的情况下才显示出这种效应。结果表明，高氯酸与硫氰化物形成氢键配合物，在硫氰化反应中活性较低。

The Effect of Proton Donors on the Process of Electrochemical Generation of Thiocyanogen and Its Reactivity

In continuation of our systematic study of the mechanism of thiocyanogen generation via electrochemical oxidation of thiocyanate anion in acetonitrile, the influence of proton donors both on the generation and on the reactivity of thiocyanogen itself was studied by experimental (cyclic voltammetry, electrolysis) and theoretical (digital simulations, quantum chemical calculations) methods. In a series of acids of various strengths (acetic, trifluoroacetic and perchloric acids), the effect was revealed only in the case of a strong proton donor, perchloric acid. It was shown that perchloric acid forms with thiocyanogen a hydrogen-bonded complex, less active in the thiocyanation reaction.
