A Green Approach for Electrochemical Thiocyanation of Nitrogen Heterocycles with KSCN at Platinum Electrode

A novel, convenient and economical method was developed for the anodic thiocyanation of nitrogen-containing aromatic and heteroaromatic compounds by constant potential electrolysis of potassium thiocyanate in an undivided cell under mild condition (25°C, Pt anode, CH3CN) with yields up to 91%. The products were characterized by spectroscopic methods and a mechanism was deduced from voltammetry studies. The salient features of proposed procedure ensures mild reaction conditions, shortest reaction time, accelerated rate, high yield, cost-effectiveness, selectivity, and simple work up procedure, Which provide additional advantages in the context of green chemistry.
