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.

Sulfoxonium ylides as safe carbene precursors are described for iridium‐catalyzed carbene insertions and annulation, providing a facile and green approach to access a variety of quinoxaline derivatives in water. This water‐mediated method also allows the preparation of β‐keto thioethers under mild condition.
