Abstract In the course of the hydrolysis of tris(alkoxy)boranes B(OR)3 (R = methyl, n-butyl, or 2-ethylhexyl) with a small amount of water in organic solvents, both possible intermediates (RO)2BOH and ROB(OH)2 have been unambiguously identified by Raman spectroscopic measurements. Lines have been found for (CH3O)2BOH at 772.8 cm -1 and for CH3OB(OH)2 at 814.6 cm -1 . The compounds are in equilibrium with the starting material B(OCH3)3 and the product B(OH)3.Potentiometrie and conductometric investigations likewise indicate the existence of these species. A mechanism of the hydrolysis reaction is based on kinetic considerations.With hydroxide ions in non-aqueous solvents or aqueous hydroxide ions the hydrolysis reactions occur differently because in the first case the end product of the hydrolysis is the orthoborate ion [B(OH)4]-, whereas in the second case in concentrated aqueous solutions poly borates are formed.
