Sažetak
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.
