Synthesis and spectral properties of hydroxy- and methoxy-substituted benzeneazophosphonates

Diethyl and dibutyl hydroxy- and methoxy-substituted [a.-(4- -benzeneazoanilino)-N-benzyl]phosphonates have been prepared. The corresponding monoesters were obtained by the partial hydrolysis of the diesters. Molecular weight determination in chloroform solution showed that the monoesters are dimeric. Infrared spectra, recorded in chloroform solution as well as in the solid state, confirmed this association as being due to the hydrogen b0nding between the P=O and P-OH group. In the hydroxy-substituted compounds, tμe phenolyc OH group also participates in such a bonding.
