Abstract: The title compound, C₂₂H₂₆BNO₃, is the first example of a boron-containing enaminone to be characterized by X-ray diffraction. The B atom lies in a three-coordinate environment and shows no additional intra- or intermolecular interactions. The 4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl group is roughly coplanar with the adjacent aromatic ring, as expected if considerable dative bonding is occurring between the aromatic p- electrons and the empty p-orbital on the B atom.
