Visible-light-mediated difunctionalization of styrenes: an unprecedented approach to 5-aryl-2-imino-1,3-oxathiolanes

The visible-light-induced straightforward synthesis of 5-aryl-2-imino-1,3-oxathiolanes from styrenes and ammonium thiocyanate is reported. The protocol utilizes air (O sub(2)) and visible light as green reagents and eosin Y as an organophotoredox catalyst. The reaction involves the formation of C-S...

Description
Summary:The visible-light-induced straightforward synthesis of 5-aryl-2-imino-1,3-oxathiolanes from styrenes and ammonium thiocyanate is reported. The protocol utilizes air (O sub(2)) and visible light as green reagents and eosin Y as an organophotoredox catalyst. The reaction involves the formation of C-S bonds followed by intramolecular C-O heterocyclization in a one-pot procedure at room temperature.
