A multi-component approach to structurally complex organosulfur products was described via the nickel-catalyzed 1,2-carbosulfenylation of unactivated alkenes with organoboron nucleophiles and tailored organosulfur electrophiles. The key to the development of this transformation was the identification of a modular N-alkyl-N-(arylsulfenyl)arenesulfonamide family of sulfur electrophiles. Tuning the electronic and steric properties of the leaving group in these reagents controls pathway selectivity, favoring three-component coupling and suppressing side reactions, as examined via computational studies. The unique syn-stereoselectivity differed from traditional electrophilic sulfenyl transfer processes involving a thiiranium ion intermediate and arose from the directed arylnickel(I) migratory insertion mechanism, as elucidated through reaction kinetics and control experiments Reactivity and regioselectivity are facilitated by a collection of monodentate, weakly coordinating native directing groups, including sulfonamides, alcs., amines, amides, and azaheterocycles.
