Schiff bases with molecular formula, HOC₆H₄CCH₃ : NXOH [where X= —CH₂CH₂ —,— CH₂CHCH₃ and C₂H₅CHCH₂ —] react with oxybis-(diacetoxyborane), [(AcO)₂,Bl₂O in 1 : 1 and I : 2 molar ratios leading to the synthesis of (SB)B —O —B(OAc)₂ and [(SB)₂B]₂O [where SB⁼ is the anion of the bifunctional tridentate Schiff base] types of the derivatives respectively. The diacetoxyboron Schiff base derivatives undergo exchange reactions with 1,2-dihydroxybenzene or 2-methyl­pentane-2,4-diol. On the basis of their elemental analyses, molecular weight determina­tions, conductance measurements and the infrared spectral studies, plausible structures have been indicated.
