Blue Light induced Coupling of N-Hydroxysulphonamides: An efficient and green Approach to Access Symmetrical Thiosulfonates

The visible light induced, highly efficient, and green protocol has been demonstrated for the synthesis of symmetrical S-Phenyl benzene thiosulfonates by irradiation of N-Hydroxy sulphonamides in the presence of ethanol solvent. The adopted method shows significant advantages such as eco-friendly procedures, short reaction time, cost effectiveness, operational simplicity, excellent yields and use of blue light which is a ubiquitous, making it a genuinely green protocol.
