An Active Catalyst System Based on Pd (0) and a Phosphine-Based Bulky Ligand for the Synthesis of Thiophene-Containing Conjugated Polymers

open access: yesFrontiers in Chemistry, 2021
To address the limitations of conventional Pd catalysts in the polymerization of thiophene-containing conjugated polymers, an active catalyst system based on Pd (0) and a phosphine-based bulky ligand, L1, is explored systematically in Suzuki–Miyaura ...

Direct Boronic Acid Promoted Amidation of Carboxylic Acids with Poorly Nucleophilic Amines

open access: yes, 2022
Direct amidation of carboxylic acids with poorly nucleophilic amines such as anilines is a notorious challenge in organic chemistry. Previously reported methodologies for direct amidation tend to report none or just a few examples with simple anilines ...

First report of Klebsiella pneumonia carbapenemase-producing Pseudomonas aeruginosa isolated from burn patients in Iran: phenotypic and genotypic methods

open access: yesGMS Hygiene and Infection Control, 2014
[english] Wound infection associated with carbapenem-resistant in burn patients is a growing problem. One of the main mechanisms of resistance to carbapenem antibiotics is the ability of to produce carbapenemase enzymes.
