Synthesis has been carried out of diarylboron chelates of 2- and 3-hydroxynitrones, of 2- and 3-hydroxyoximes, and of 2-carboxynitrones and a 2-carboxyoxime. The structures have been determined from spectroscopic data and from X-ray analyses of 5d, 9a, 11b, and 19. Crystals (at 180 K) of 5d are monoclinic, a = 10.543(2), b = 19.085(4), c = 10.2667(3) Å, β = 90.4978(7)°, Z = 4, space group P21/c; those of 9a are orthorhombic, a = 10.9913(5), b = 14.9329(7), c = 10.2460(13) Å, Z = 4, space group P212121; those of 11b are monoclinic, a = 11.227(2), b = 9.967(2), c = 17.0537(4) Å, β = 105.4179(5)°, Z = 4, space group P21/n; those of 19 are monoclinic, a = 11.1847(15), b = 13.715(3), c = 11.5559(5) Å, β = 104.8730(10)°, Z = 4, space group P21/n. The structures were solved by direct methods and refined by full-matrix least-squares procedures to R(F, I [Formula: see text] 3σ(I)) = 0.049, 0.047, 0.042, and 0.047, respectively, for CCD data for 5d, 9a, 11b, and 19. The four molecules contain five-, seven-, six-, and five-membered rings, respectively, with O-B-N groups in the 5d, 11b, and 19, and O-B-O in 9a; the rings exhibit various deviations from planarity, particularly the seven-membered ring.Key words: diarylboron chelates, hydroxyoximes, hydroxynitrones, carboxyoximes, carboxynitrones, organoboron compounds, crystal structure.
The synthesis of a number of variously substituted N-alkyl 2-hydroxyaminoalkanols 3 and their reactions with phenylboronic acid are detailed. The crystalline products proved to be 1:2 condensates 4 in a few cases and 1:1 condensates 5 in all the other cases studied. Crystals of 2-mesityl-6,6-pentamethylene-1,3-dioxa-4-aza-2-boracyclohexane, 5l, are triclinic, a = 11.540(2), b = 10.402(3), c = 8.440(2) Å, α = 108.86(2)°, β = 97.62(2)°, γ = 89.36(2)°, Z = 2, space group [Formula: see text] and those of 4,4′-methylenebis(6,6-pentamethylene-2-phenyl-1,3-dioxa-4-aza-2-boracyclohexane) benzene solvate, 15a•C6H6, are monoclinic, a = 22.690(1), b = 16.867(1), c = 8.4783(9) Å, β = 104.912(8)°, Z = 4, space group C2/c. The structures were solved by direct methods and refined by full-matrix least-squares procedures to R = 0.037 and 0.035 (Rw = 0.035 and 0.044) for 3190 and 2084 reflections with I ≥ 3σ(F2)• respectively.
