The title reaction was conducted in a two-phase system of dichloromethane and water using a tetrabutylammonium halide as a phase-transfer catalyst.The reaction of the photogenerated arylvinyl cation with cyanate ion gave only isoquinolone derivatives, whereas the reaction with thiocyanate ion afforded products derived from S attack, vinyl thiocyanates, and products derived from N attack, vinyl isothiocyanates or thioisoquinolones.The ambident nature of thiocyanate ion is compared with the reaction of benzyl bromides.

Photolysis of vinyl bromides with cyanate anion in a two-phase system gave only isoquinolinones as the N-site attacked products.However, the photolysis with thiocyanate anion gave the N-site attacked products, isothioquinolinones or vinyl isothiocyanates, and the S.site attacked products, vinyl thiocyanates.
