Abstract

Recent advances using nickel complexes in the activation of unactivated monosubstituted olefins for catalytic intermolecular carbon-carbon bond-forming reactions with carbonyl compounds, such as simple aldehydes, isocyanates, and conjugated aldehydes and ketones, are discussed. In these reactions, the olefins function as vinyl- and allylmetal equivalents, providing a new strategy for organic synthesis. Current limitations and the outlook for this new strategy are also discussed.

The mixture was stirred for 48 h at r.t. The yields and ratios were determined by ¹H NMR analysis of the crude reaction mixture.

  • It was shown that certain organophosphorus compounds accelerate reductive elimination from a nickel complex (albeit not in a catalytic reaction). The authors attributed the effect to the size of the phosphorus additive rather than its electronic nature:

  • The effects of phosphorus ligands upon reductive elimination from [Ni(NHC)alkyl] complexes to give alkyl imidazolium salts have been studied. In contrast, our observation that the NHC was not consumed suggests that one of the other ligands (for example H or OTf) significantly affects the properties and behavior of the metal complex:
