A simple procedure affording benzoates through a NHC‐catalyzed aerobicoxidativeesterification of aldehydes with organoboronic acids has been disclosed. This process allows access to a wide variety of aromatic esters in good to excellent yields under simple, efficient, and sustainable reaction conditions (see scheme).

ionic-liquid-supported diaryliodoniumsalts is described. The synthesis is simple and practical, and the ionic liquid products require no chromatographic purification. The ionic-liquid-supported diaryliodoniumsalts are quite stable, and they did not show any sign of decomposition or loss of reactivity, even after being stored for one month at 5 °C. The reactivity of these salts was explored in the phenylation of substituted
The synthesis, characterization and antimicrobialevaluation of a new series of veratric acid derivatives are presented. Preliminary in vitro antimicrobial activity of the title compounds was assessed against a panel of microorganisms including Gram-positive and Gram-negative bacteria and fungi. Some of the veratric acid derivatives exhibited significant in vitro antimicrobial activity. QSAR investigation
