The present invention relates to a method for preparing a four-coordinated organic boron compound, and more specifically, to a method for preparing various and widespread four-coordinated organic boron compounds by directly using an aryl, heteroaryl, or vinyl-functional boronic acid, boroxine, or borate compound as a starting material and adding the compound to any bidentate N,O-ligand, O,O-ligand, or N,N-ligand.

method for the preparation of diphenylboron chelates from ammonium tetraphenylborate is described. A variety of five- or six-membered O,O-, N,O- and N,N-chelates were obtained in yields from 60 to 90 %. The isolated compounds were characterized by elemental analysis, IR spectroscopy and multinuclear magnetic resonance spectroscopy (1H, 13C, and 11B). The crystal and molecularstructures of (pyridine

telescoped process has been developed for practical preparation of N,O-chelated four-coordinate diarylborinates via direct reaction of N,O-chelate ligands with a diarylborinate solution prepared by removal of magnesium via precipitation from a one-pot reaction of aryl bromides, magnesium, and tributylborate. Ten N,O-chelated diarylborinates of representative N,O-chelate ligands of 2-picolinic acid, quinolin-8-ol
