| Abstract: | A general preparative procedure for polyfluorinated aryl(dihydroxy)boranes C6H5‐nFnB(OH)2 (n = 3 — 5) is described. Polyfluorinated aryl(dihydroxy)boranes are easily dehydrated to the corresponding tri(aryl)boroxins (C6H5‐nFnBO)3 by thermal or chemical treatment. The property of the acids C6H5‐nFnB(OH)2 to condensate depends on the number and on the position of the fluorine atoms in the aryl group. Examples of both classes of boron compounds were isolated as pure individuals and characterized by multinuclear NMR spectroscopy. |
