ABSTRACT
The title compound, (E)-methyl-4-[(2-phenylhydrazono)methyl]benzoate, (I), (C15H14N2O2), has been synthesized by condensation reaction of methyl-4-formylbenzoate and phenylhydrazine. The compound has been characterized by elemental analysis, IR, (1)H NMR, (13)C NMR, UV-Vis spectroscopies and single crystal X-ray diffraction techniques. Optimized molecular structure, harmonic vibrational frequencies, (1)H and (13)C NMR chemical shifts have been investigated by B3LYP/6-31G(d,p) method using density functional theory (DFT). Global chemical reactivity descriptors, natural population analysis (NPA), thermodynamic and non-linear optical (NLO) properties have also been studied. The energetic behavior of the compound has been examined in solvent media using the integral equation formalism polarizable continuum model (IEF-PCM).

The pyrrolidine and morpholine enamines of cyclic ketones such as cyclohexanone and cyclopentanone were successfully diacetylated at alpha- and alpha'-positions with trichloroacetyl chloride using zinc catalyst. Morpholine enamines of the cyclic ketones gave acetylated morpholine in good yields besides the corresponding diacetylated cyclic enamines. When the same reactions were performed by using triethylamine without using zinc, monoacetylation products of the same enamines were synthesized.
