Beyond Traditional Cross Couplings: The Scope of the Cross Dehydrogenative Coupling Reaction [PDF]

open access: yesChemistry – An Asian Journal, 2010
AbstractThe development of new and environmentally compatible methods for the synthesis of CC and Cheteroatom bonds is of great significance to researchers. The cross dehydrogenative coupling (CDC) is emerging as an important tool for chemists with a variety of, often inexpensive, metal catalysts able to perform these reactions both regio‐ and ...

A New Heterogeneous Catalyst Obtained via Supramolecular Decoration of Graphene with a Pd2+ Azamacrocyclic Complex

open access: yesMolecules, 2019
A new G-(H2L)-Pd heterogeneous catalyst has been prepared via a self-assembly process consisting in the spontaneous adsorption, in water at room temperature, of a macrocyclic H2L ligand on graphene (G) (G + H2L = G-(H2L)), followed by decoration of the ...

Imine Palladacycles: Synthesis, Structural Analysis and Application in Suzuki–Miyaura Cross Coupling in Semi-Aqueous Media

open access: yesMolecules, 2022
Treatment of the imines a–c with palladium(II) acetate in acetic acid yielded the μ-acetate dinuclear complexes 1a–c, which readily reacted with sodium chloride or bromide to provide μ-halide analogues.

Deaminative vinylation and arylation cross-coupling reactions

open access: yes, 2023
Watson, Mary P.This thesis focuses on nickel-catalyzed vinylation and arylation cross-coupling reactions via C-N bond activation. Chapter 1 describes a vinylation method that was inspired by an analogous alkylation.

Cross-Electrophile Coupling of Alcohols with Aryl and Vinyl Halides [PDF]

open access: yes, 2021
Although alcohols represent one of the largest pools of commercially available alkyl substrates, approaches to di-rectly utilize them in cross-coupling and cross-electrophile coupling are limited.

Advanced Filtering Solutions in Coaxial SIW Technology Based on Singlets, Cascaded Singlets, and Doublets

open access: yesIEEE Access, 2019
The use of singlets, cascaded singlets, and doublets in a coaxial substrate integrated waveguide (SIW) technology is proposed in this paper, with the aim of implementing low-loss filters with very compact size and highly selective symmetric, asymmetric ...
