Significance
Zhu and coworkers report an enantioselective synthesis of organoboron compounds via the α-boryl carbene. This work expands on the scarcely used α-boryl carbene intermediate in a wide range of applications.

Comment
While investigating the mechanism, KIE studies revealed that the rate-determining step was likely the cyclopropene ring opening. Interestingly, it is suggested that the α-boryl carbene is likely a donor-type carbene when compared to the known α-ester and hydrogen carbenes.
