A redox-relay migratory hydroarylation of isomeric mixtures of olefins with arylboronic acids catalyzed by nickel complexes bearing diamine ligands is described. A range of structurally diverse 1,1-diarylalkanes, including those containing a 1,1-diarylated quaternary carbon, were obtained in excellent yields and with high regioselectivity. Preliminary experimental evidence supports the proposed non-dissociated

We report the hydrofluorination of unactivated alkenes using N-fluorobenzenesulfonimide as a fluorination reagent. The reaction produces exclusively Markovnikov hydrofluorination products under mild conditions. It is not affected by air or moisture and uses an inexpensive and readily available nickel compound as a catalyst. Distinct from the previously reported ionic pathway of the NiH-catalyzed h
