摘要：
The standard massic energies of combustion of two borinic esters containing the intramolecular N→B bond having different stabilities were determined by oxygen rotating-bomb combustion calorimetry. The studied compounds were: diphenyl(2-pyridylmethoxy-O, N)borane (A1) and diphenyl {2-(2’-pyridyl)ethoxy-O, N}borane (A2). Based on the experimental results, the standard molar enthalpies of formation were determined as: ΔfHom{C18H16ONB(A1), cr} = -(194.6 ± 4.9}kJ·mol-1 and ΔfHom{C19H18ONB(A2), cr} = -(171.8 ± 3.2)kJ· mol-1. © 1994 Academic Press Ltd.
