Although polyethylene (PE) and polypropylene (PP) are by far the world's largest volume plastics, only a tiny fraction of these energy-rich polyolefins are currently recycled. Depolymerization of PE to its constituent monomer, ethylene, is highly end

Nickel(0) catalysts of N-heterocyclic carbenes (NHCs) that are stabilized by electron-deficient alkenes possess desirable properties of air tolerance and ease of handling while also retaining high catalytic activities. Since catalyst stability often

The efficient copolymerization of acrylates with ethylene using Ni catalysts remains a challenge. Herein, we report two neutral Ni(II) catalysts (POP-Ni-py (1) and PONap-Ni-py (2)) that exhibit high thermal stability and significantly higher incorpor

Copper, an earth-abundant metal, has reemerged as a viable alternative to the versatile Pd-catalyzed C–N coupling. Coupling sterically hindered reaction partners, however, remains challenging. Here...

A detailed mechanistic investigation of N-heterocyclic carbene-nickel-catalyzed hydroarylation via C–H functionalization is described. These catalysts are complicated, in part, by undesired reactivity stemming from common olefinic ligands such as c

The living, chain-growth polymerization of (hetero)aryl monomers by carbene-ligated palladium precatalysts gives conjugated polymers with narrow dispersities as well as specified molecular weights and sequences. Despite this success, the mechanism fo

The synthesis and catalytic activity of several classes of NHC–Ni(0) pre-catalysts stabilized by electron-withdrawing alkenes are described. Variations in the structure of fumarate and acrylate ligands modulate the reactivity and stability of the N

An inhibitory role of 1,5-cyclooctadiene (COD) in nickel-catalyzed C-H functionalization processes was identified and studied. The bound COD participates in C-H activation by capturing the hydride, leading to a stable off-cycle π-allyl complex that

Deoxygenative coupling of enones or enals with alkynes is rendered possible with a reagent combination of Et3SiH and Ti(OiPr)4 and a nickel carbene complex as catalyst furnishing skipped dienes in moderate to good yields.
