Copper acetate mediated α-oxysulfonylation of α-diazo β-ketosulfones in wet nitromethane under nitrogen provides α-oxysulfonyl β-ketosulfones. The use of different copper salts is investigated for the development of a facile and efficient transformation. A plausible mechanism is proposed herein.
Highly efficient visible-light initiated direct oxysulfonylation of alkenes with sulfinic acids leading to β-ketosulfones has been realized under metal-free conditions.
