A highlyselectivePd/Cu‐cocatalyzed aerobicoxidativecarbonylativehomocoupling of arylboronicacids has been developed. This method employs a simple catalytic system, readily available boronic acids as the substrates, molecular oxygen as the oxidant, and 1 atm of CO/O2, which makes this method practical for further applications.

A process of making furfural-derived ketones is disclosed. These compounds may be useful as marine antifouling agents. The process uses the steps of: reacting a furfural with 1,3-dithiopropane to form a 1,3-dithiane derivative; metalizing the 1,3-dithiane derivative to form a metalodithiane derivative; reacting the metalodithiane derivative with a halide or pseudohalide to form a ketone precursor; and hydrolyzing the ketone precursor to form a furyl ketone.

palladium acetate-catalyzed coupling reaction of aryl boronic acid with carboxylic anhydride or acyl chloride was carried out smoothly in water in the presence of poly(ethylene glycol) (PEG) or 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) to give high yields of ketones without the use of phosphine ligands. The Pd(OAc)2−H2O−[bmim][PF6] catalytic system can be recovered and reused eight
