Abstract
A simple synthesis of thiocyanated aromatics has been developed by using heteroaromatic azo compounds such as 2,2′-azobenzothiazole as a mild and heterogeneous oxidant. The reactions proceed at room temperature with good regioselectivity. The hydrazine by-product can be easily separated by filtration and recycled for further use.
