Excited states and absorption spectra of 2-β-diketonato-1,3,2-benzodioxaborol with aromatic substituents: Quantum-chemistry modeling
2015, Spectrochimica Acta - Part A: Molecular and Biomolecular SpectroscopyCitation Excerpt :The bicyclic borates have perpendicular π-systems through four bonds of B–O. That‘s why researchers pay much attention to the issues of distribution of the electron density, the charge transfer, and, as a result of this effects, the change of the aromatic characteristics of the ligands. The literature contains rather detailed information on UV, NMR and IR spectroscopy for some spiro-borates [5,10–12], as well as X-ray diffraction of some of their representatives [13]. β-Diketones have a high complexing ability [14], and are used in the synthesis of dyes, phosphors, and for the extraction processes of heavy metals.
Monocyclic hetarenes with φ-electron aromatic sextet
2010, Advances in Heterocyclic ChemistryCitation Excerpt :On replacing an –RCCR– bond in pyrylium cations by an –RBO– bond, one should obtain boroxaropyrylium (1,3,2-dioxaborinium) cations. The crystalline perchlorates (64TL2721, 65TL3917, 65TL3925, 67SA1373, 68T2499), revealed by X-ray diffractometry, however, an unexpected feature, namely one of the perchlorate oxygens is attached covalently to the diazaborinium cation resulting in a neutral system (83ZNA1161, 06ZNA360). The first six-membered aromatic heterocycles containing one boron atom together with a second heteroatom (oxygen or nitrogen, namely boroxaro- and borazaro-derivatives, respectively) were prepared by Dewar and Pettit in 1955–1956 (55CIL199, 56JCS2021, 56JCS2026).
