The enantiomers of [2-(dimethylaminomethyl)phenyl](pentafluoropropionyloxy)phenylborane were successfully resolved by chiral HPLC as a new type of intramolecular amine–borane complex with a chiral center at the tetrahedral boron atom. The X-ray structure, the barrier to racemization, and the chiroptical properties are reported.
