Photo‐Induced Thiocyanation and Selenocyanation of Alkenylthianthrenium Salts

ABSTRACT Organic selenocyanates and thiocyanates are important organic synthetic intermediates. Herein, we report a simple synthetic method for preparing styrenyl selenocyanates/thiocyanates from alkenylthianthrenium salts under photochemical reaction conditions, features simple manipulation and mild conditions, without the need for photocatalyst or single electron donor. This method provides a green new approach for the synthesis of organic selenium/sulfur compounds.
