A combinatorial nickel-catalyzed cross-coupling between arylboronic acids and unactived 1-fluoro-1-iodoalkanes has been developed, which demonstrated high efficiency, mild conditions, and excellent functional-group compatibility. Readily available nitrogen and phosphine ligands were combined with a nitrogen source, which in situ generated a variety of easily tunable catalysts to promote the fluoroalkylation

The light-induced, Ru-catalyzed three-component alkyl-fluorination of olefins under mild reaction conditions is reported. This carbofluorination reaction features a wide substrate scope and good functional group tolerance. A key advantage of this photoredox reaction is the use of nucleophilic fluoride and generic alkyl groups. Late-stage functionalizations are achieved, and a copper-assisted oxidative

bidentate and monodentate pyridine‐type nitrogen ligands with nickel, which in situ generated a variety of readily tunable catalysts to promote fluoroalkylation with broad scope with respect to both coupling partners. This combinatorial catalysis strategy offers a solution for nickel‐catalyzedreductivecross‐coupling reactions and provides an efficient way to synthesize fluoroalkylated druglike molecules
