摘要

reaction of 4-tert-butylphenoxyacetylhydrazide with aromatic aldehydes and acetone a new series of 4-tert-butylphenoxyacetylhydrazones was synthesized. The structural peculiarities of the investigated molecules have been determined by means of X-ray analysis and IR spectroscopy. The diagnostically important IR spectral criteria required for the conformational analysis of acethylhydrazones have been considered. It was established that the 4-tert-butylphenoxyacetylhydrazide in condensed phase exists only as a Z(N-C(O))-conformer. Its derivatives exist as EN-C(O) and Z(N-C(O))-forms. As a rule, the prevalence of Z(N-C(O))-form has been observed in CCl4 solutions. The structure of investigated compounds is also determined by a system of inter- and intrantolecular hydrogen bonds. The energy of hydrogen bonds was estimated. (c) 2006 Elsevier B.V. All rights reserved.
