The invention relates to N-hydroxysulfonamide derivatives that donate nitroxyl (HNO) under physiological conditions and are useful in treating and/or preventing the onset and/or development of diseases or conditions that are responsive to nitroxyl therapy, including heart failure and ischemia/reperfusion injury. Novel N-hydroxysulfonamide derivatives release NHO at a controlled rate under physiological conditions, and the rate of HNO release is modulated by varying the nature and location of functional groups on the N-hydroxysulfonamide derivatives.

A hydrosulfonylation reaction of unactivated alkenes with sulfinicacids was realized under light irradiation. This reaction features photocatalyst- and additive-free conditions. A diverse set of unactivated alkenes can be transformed into alkyl-substituted sulfones with good yields and anti-Markovnikov regioselectivity. The present protocol was amenable to gram-scale synthesis, as well as late-stage
