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.

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 ...

Gender Asymmetries in Cross‐National Couples

open access: yesPopulation and Development Review, 2023
AbstractWe use census microdata for Spain and the United States to examine gender differences in cross‐national heterosexual couples (marriages and cohabitating unions involving natives and immigrant spouses). We examine whether native men and native women in cross‐national couples exhibit similar patterns regarding the country of birth, age, and ...

Synthesis of chiral germanium center enabled by poly-deborylative alkylation and desymmetrization

open access: yesNature Communications
Chiral germanium centers are historically undervalued due to their extremely limited synthetic accessibility. Although germanium shares similar chemical properties with silicon, synthesizing chiral germanium centers proves significantly more challenging.
