  Abstract: The title compd. is the 1st example of   a B-contg. enaminone to be characterized by x-ray diffraction.   Crystals of the compd. are triclinic, space group P̅1, with a   5.9593(3), b 13.4318(12), c 14.4116(13) Å, α 117.219(1), β   92.646(2), γ 98.159(2)°; Z = 2, dc = 1.198; R = 0.039, Rw(F2) =   0.103 for 4397 reflections. The B atom lies in a three-coordinate   environment and shows no addnl. intra- or intermol. interactions.   The 4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl group is roughly   coplanar with the adjacent arom. ring, as expected if   considerable dative bonding is occurring between the arom. p-π   electrons and the empty p-orbital on the B atom.
