Under transition-metal-free conditions, carbonylative Suzuki couplings of arylhalides with arylboronic acid using stoichiometric CHCl3 as the carbonyl source has been developed. The simple, efficient, and environmentally benign method was successfully applied to the synthesis of Fenofibric acid, naphthyl phenstatin, and carbon-13 labeled biaryl ketone.

Erbium trifluoromethanesulfonate is found to be a good catalyst for the Friedel–Craftsacylation of arenes containing electron-donating substituents using aromatic carboxylicacids as the acylating agents under microwave irradiation. An effective, rapid and waste-free method allows the preparation of a wide range of aryl ketones in good yields and in short reaction times with minimum amounts of waste

cross-coupling of aromatic carboxylicanhydrides or acid chlorides with triarylboroxines has been achieved for the first time under decarbonylation, giving rise to the unsymmetrical biaryls rather than the expected diaryl ketones. This newdecarbonylative Suzuki coupling, catalyzed by a [Rh(ethylene)2Cl]2/KF system, can be applied to aromatic, heteroaromatic and vinylic carboxylicanhydrides, potentially opening
