A visible-light-promoted atomic substitution reaction for transforming thiocacids into carboxylic acids with dimethyl sulfoxide (DMSO) as the oxygen source has been developed, affording various alkyl and aryl carboxylic acids in over 90% yields. The atomic substitution process proceeds smoothly through the photochemical reactivity of the formed hydrogen-bonding adduct between thioacids and DMSO. A DMSO-involved proton-coupled electron transfer (PCET) and the simultaneous generation of thiyl and hydroxyl radicals are proposed to be key steps for realizing the transformation.

Background: Prosthetic joint infection is a serious complication that can arise after total joint replacement surgery. When bacteria colonise an orthopaedic implant, they form biofilms that protect them from their environment, making them difficult to remove. Treatment is further complicated by a global rise of antimicrobial resistance.

Recently, researchers have used silver nanoparticles (AgNPs) coupled with humic acid (HA) as antimicrobial agents. Herein, AgNPs were prepared and coupled with humic acid for their antimicrobial activities. The as-prepared AgNPs coupled with humic acid (HA) were characterized by an atomic force microscope (AFM), X-ray powder diffraction (XRD), zeta potential, zeta sizer, Fourier-transform infrared (FT-IR) spectroscopy, and UV-VIS spectrophotometer.

An atmospheric oxygen-mediated oxidative coupling of primary and secondary alcohols for the synthesis of nitrogen-containing heterocycles has been developed. This method utilizes atmospheric oxygen as the sole, environmentally friendly oxidant to convert a variety of alkyl and aromatic primary alcohols into aldehyde equivalents, avoiding over-oxidation to carboxylic acids. Notably, these mild oxidation conditions are compatible with both primary and secondary alkyl alcohols as substrates.

The present study describes the use of the di--butyl dicarbonate (BocO)/4-(,-dimethylamino)pyridine (DMAP) system for the amidation of carboxylic acids under neat conditions without heating. A set of carboxylic acids was explored, such as non-steroidal anti-inflammatory drugs (NSAIDs), fatty acids and protected prolines in the presence of aromatic, benzylic and aliphatic amines as nucleophilic partners. The scope of this easy approach was extended to the preparation of thirty-two diverse carboxylic amides, which were recovered with isolated yields varying from moderate to excellent.
