the byproduct succinimide from ‘waste water’ can be conveniently converted into the starting reagent N-chlorosuccinimide with sodium hypochlorite (bleach) to make the method sustainable. A convenient, practical, and environmentally friendly method for the synthesis of sulfonyl chlorides has been developed. Structurally diverse sulfonyl chlorides were synthesized in moderate to excellent yields from

described. The transition-metal-free approach, readily available reagents, and mild conditions provide a practical way for the synthesis of difluoromethylthioethers. By changing the “H” source to the most commonly used “D” sources CD3OD and D2O, this strategy enables efficient synthesis of SCF2D-substituted molecules in good yields with high levels of D incorporation.
