Ultrasound has been successfully employed to promote the thiocyanation of C═C bond in enaminones for synthesis α-thiocyanoketones and 2-aminothiazoles. The reactions with ammonium thiocyanate provide ultrasound irradiation at room temperature. More interestingly, simply further heating vessel after ultrasonic leads selective 2-aminothiazoles an unconventional 4-aryl substructure.

Visible light photocatalytic reactions of NH2-enaminones and ammonium thiocyanate for chemoselective α-C-H thiocyanation have been realized the first time, providing a sustainable route synthesis thiocyanated NH2-enaminones. In addition, enaminone products can be flexibly transformed into 2-aminothiazoles 2-thiazolinones via simple operation.
