AI Article Synopsis
- A new method has been developed to create the first Xantphos nickel complexes with alkynes and alkenes, which is a significant advancement in this field.
- NMR studies revealed that benzonitrile can replace a Xantphos ligand in the (Xant)2Ni complex, challenging the previous belief that this compound was inactive.
- The nickel π-complexes were found to be effective catalysts for cross coupling and cycloaddition reactions, especially when activated by a nitrile or a coordinating solvent.
Article Abstract
A general synthetic route to the first Xantphos nickel alkyne and alkene complexes has been discovered. Various Ni π-complexes were prepared and characterized. NMR experiments indicate benzonitrile undergoes ligand exchange with a Xantphos ligand of (Xant)2Ni, a compound that was previously believed to be unreactive. The Ni π-complexes were also shown to be catalytically competent in cross coupling and cycloaddition reactions. (Xant)2Ni is also catalytically active for these reactions when activated by a nitrile or coordinating solvent.

Unprecedented regioselective -hydroboration and carboboration of unbiased electronically internal alkynes were realized a nickel catalysis system with the aid of the directing group strategy. Furthermore, the excellent α- and β-regioselectivity could be accurately switched by the nitrogen ligand (terpy) and phosphine ligand (Xantphos). Mechanistic studies provided an insight into the rational reaction process, that underwent the -to- isomerization of alkenyl nickel species.

We describe here the development of a visible light driven nickel carbonylation catalyst. The combination of the large bite-angle Xantphos ligand with nickel(0) generates a catalyst capable of activating alkyl halides toward carbonylation at ambient temperature in the presence of blue light irradiation, and the reductive elimination of high energy acid chloride products. Unlike classical carbonylations, where the coordination of carbon monoxide inhibits the reactivity of earth abundant nickel catalysts, a CO-associated nickel is found to be the active catalyst in the reaction.

An air-tolerant nickel-catalyzed cyanation of aryl bromides is reported. The reaction uses a NiCl/Xantphos catalyst in combination with substoichiometric quantities of zinc cyanide and polymethylhydrosiloxane. This silane is a green, homogeneous alternative to the traditional, insoluble solid reductant zinc and renders the reaction tolerant to air.

Ni(COD)-catalyzed cycloaddition reactions to access pyridines have been extensively studied. However, this catalyst typically requires drying procedures and inert-atmosphere techniques for the reactions. Herein, we report operationally simple nickel(0) catalysis to access substituted pyridines from various nitriles and 1,6-diynes without the aid of air-free techniques.

A critically important process in catalysis is the formation of an active catalyst from the combination of a metal precursor and a ligand, as the efficacy of this reaction governs the amount of active catalyst. This Review is a comprehensive overview of reactions catalyzed by nickel and an added bidentate phosphine, focusing on the steps transforming the combination of precatalyst and ligand into an active catalyst and the potential effects of this transformation on nickel catalysis. Reactions covered include common cross-coupling reactions, such as Suzuki, Heck, Kumada, and Negishi couplings, addition reactions, cycloadditions, C-H functionalizations, polymerizations, hydrogenations, and reductive couplings, among others.
