Borate esters
Borate esters are organic compounds which are conveniently prepared by the stoichiometric condensation reaction of boric acid with alcohols. There are two main classes of borate esters: orthoborates, B(OR)3 and metaborates, B3O3(OR)3. Metaborates contain 6-membered boroxine rings. B(OH)3 + 3 ROH → B(OR)3 + 3 H2O3 B(OH)3 + 3 ROH → B3O3(OR)3 + 6 H2O Borate esters form spontaneously when treated with diols such as sugars and the reaction with mannitol forms the basis of a titrimetric analytical method for boric acid. ArMgBr + B(OCH3)3 → MgBrOCH3 + ArB(OCH3)2ArB(OCH3)2 + 2H2O → ArB(OH)2 + 2HOCH3
