용도Tetraacetyl Diborate (TADB) is used as a selective acetylating agent for aromatic polyhydroxycarbonyl compounds; mild Lewis acid for Diels-Alder reactions of hydroxyquinones.
Preparative Methods of Tetraacetyl Diborate: a mixture of 31 g (0.50 mol) of Boric Acid and 165 mL (1.75 mol) of Acetic Anhydride is heated slowly with an oil bath under N2 in a flask equipped with a reflux condenser and a magnetic stirrer. At about 70 °C a vigorous exotherm (CAUTION) occurs and the reaction mixture becomes a clear solution which, upon cooling, deposits crystals of TADB. The supernatant is drawn off and the crystals either washed with dry ether or recrystallized from 200 mL CHCl3/benzene.[1]
