Visible-light-mediated additive-free decarboxylative functionalization of acrylic acids has been developed. The reaction uses inexpensive organic dye 9,10-dicyanoanthracene as a photocatalyst and uses the ubiquitous dioxygen as both an oxygen source and an oxidant. Through this mild and environmentally friendly method, a series of important α-thiocyanate ketones can be generated from easily available acrylic acids and ammonium thiocyanate. In addition, the facile transformation of product α-thiocyanate ketones makes this method have great potential for application in organic and pharmaceutical chemistry.

Mesoporous graphitic carbon nitride (mpg-C3N4) has been developed as a metal-free heterogeneous photocatalyst for thiocyanation transformations. The reaction proceeds efficiently by utilizing air as a green oxidant under mild reaction conditions, which affords SCN-containing compounds in moderate to excellent yields. Meanwhile, the practicality of this protocol is further demonstrated by the reusability of the mpg-C3N4photocatalyst and the scaled-up reaction. Furthermore, detailed mechanistic studies clearly demonstrate the role of oxygen.

A simple and convenient visible-light-induced difunctionalization of alkenes with ammonium thiocyanate and dioxygen has been developed at room temperature. A series of α-thiocyanato ketones could be easily and efficiently obtained in moderate to good yields through the formation of C-S and C=O bonds simply by using nontoxic and inexpensive Na 2 -Eosin Y as a photocatalyst.
