Carbonylative coupling of aryl tosylates/triflates with arylboronic acids under CO atmosphere

Abstract

The carbonylative Suzuki–Miyaura reaction between aryl tosylates/triflates with arylboronic acid is herein reported, using base-free conditions and a balloon pressure of carbon monoxide. Under these conditions, unsymmetrical biaryl ketones were obtained in modest to excellent yields. This method was adapted to the synthesis of oxybenzone and ketoprofen in good yields under mild conditions.
