An efficient and mild method is developed for radicaldeoxygenation of alcohols and formation of carbon–carbon bonds in water without adding additives such as surfactants. The reaction was applied to synthesis of 2′,3′-didehydro-2′,3′-dideoxynucleosides that are potent anti-HIV agents. The reaction afforded environmentally benign reaction conditions.

N-Ethylpiperidine hypophosphite mediated radical addition reactions to electron deficient alkenes in aqueous media have been developed. The reactions afford high isolated yields of addition products without using a large excess of alkenes.

hydrosulfonylation of unactivated alkenes with sodium sulfinates was realized via [Ir(dF(CF3)ppy)2(dtbbpy)]PF6-mediated visiblelightphotoredoxcatalysis. The presence of an acid such as acetic acid is essential for the reaction to take place. A variety of unactivated alkenes can be transformed into sulfones with good yield and high regioselectivity using this reaction, which is proposed to proceed by a radical
