Visible Light‐Promoted Esterification of Carboxylic Acids via Photoacid Generation Catalysis

Advanced Synthesis &Catalysis, EarlyView.
A novel, environmentally friendly photochemical method for the esterification of carboxylic acids with alcohols using arylazo sulfones as photoacid generators was developed. This approach avoids traditional acidic catalysts, purification did not require chromatography and the method proved effective under continuous flow conditions for enhanced ...

Synthesis of Spirolactones from Carbonyls via Carboborylation of N‐Sulfonylhydrazones with Alkoxycarbonylalkylboronic Acids

Advanced Synthesis &Catalysis, EarlyView.
Spirolactones are readily prepared from carbonyls via their N‐tosylhydrazones. The reaction involves carboborylation with ethoxycarbonyl‐substituted boronic acids, followed by oxidation and lactonization. Thermal or photochemical protocols enable versatility.

C–H Homocoupling of Arenes via Pd/S,O‐Ligand Catalysis

Advanced Synthesis &Catalysis, EarlyView.
An efficient C‐H homocoupling of arenes via Pd/S,O‐ligand catalytic system is reported. This method can be applied to a series of arenes using O2 as oxidant under room temperature and is also applicable for late‐stage homocoupling of pharmaceutical derivatives.
