Evidence for alkene cis-aminocupration, an aminooxygenation case study: Kinetics, EPR spectroscopy, and DFT calculations
Alkene difunctionalization reactions are important in organic synthesis. We have recently shown that copper(II) complexes can promote and catalyze intramolecular alkene aminooxygenation, carboamination, and diamination reactions. In this contribution, we

Nickel-catalyzed cycloisomerization of enynes: catalyst generation via C-H activation of carbene ligands
The combination of Ni(0) and an N-heterocyclic carbene acts as a precatalyst for the cycloisomerization of enynes to afford 1,3-dienes. During the course of the reaction, a nickel hydride is formed from oxidative addition of the ortho C-H on the carbene ligand. Deuterium labeling studies are presented. Crown Copyright
