An iridium-catalyzed B-H bond insertion reaction between borane adducts and sulfoxonium ylides to afford α-boryl carbonyls has been developed. The starting materials are safe and readily available. In addition, analogues of sulfoxonium ylides, such as sulfonium salts and sulfonium ylides could also be amenable to the reaction.
