New Frontiers in Alkali-Metal Nickelates

Autor: Andryj M. Borys, Eva Hevia

Publikováno v: CHIMIA, Vol 77, Iss 4 (2023)

Recent advances in heterobimetallic chemistry have revealed the potential for mixed-metal systems to facilitate reactions that are unattainable with their single-metal components. This perspective explores the pairing of nickel(0) complexes with orga

Diphenylacetylene stabilised alkali-metal nickelates: synthesis, structure and catalytic applications

Autor: Andryj M. Borys, Eva Hevia

Publikováno v: Dalton Transactions. 52:2098-2105

Using diphenylacetylene as a π-accepting ligand allows access to a new family of alkali-metal nickelates, which can effectively promote the [2 + 2 + 2] cyclotrimerisation of diphenylacetylene.

Atom-efficient arylation of N-tosylimines mediated by cooperative ZnAr2/Zn(C6F5)2 combinations

Autor: Andryj M. Borys, Tim Kunzmann, Jose M. Gil-Negrete, Eva Hevia

Publikováno v: Chemical Communications.

Operating via a special type of Zn/Zn′ cooperation, an atom-efficient method for the arylation of N-tosylimines has been developed combining nucleophilic ZnAr2 with Lewis acidic Zn(C6F5)2.

Summary While 1,4-disubstituted 1,2,3-triazoles can be readily prepared by copper(I) alkyne/azide cycloaddition, the methods available to access the alternative 1,5-disubstituted isomers have been significantly less well developed. Exploiting chemica

The Ni‐catalysed cross‐coupling of aryl ethers is a powerful method to forge new C−C and C−heteroatom bonds. However, the inert C(sp2)−O bond means that a canonical mechanism that relies on the oxidative addition of the aryl ether to a Ni0
