Two new phenol-based ester derivatives, namely C13H9ClO2 (I) and C20H14O4 (II) have been synthesized and characterized by NMR spectroscopy, single crystal X-ray diffraction and density functional theory (DFT) geometry optimization and molecular orbital calculations. Compound I crystallizes in the orthorhombic space group Pca2(1),with a = 7.6297 (5) ?, b = 5.5875 (3) ?, c = 26.1624 (12) ?, α = β = γ = 90°, V = 1115.33(11) ?3 and Z = 4. Compound II crystallizes in the triclinic space group P $βar 1$$ 1 ˉ, with a = 5.7970 (4) ?, b = 8.1366 (8) ?, c = 8.8057 (9) ?, α = 83.246 (8)°, β = 72.138 (8)°, γ = 76.696 (8)°, V = 384.22 (6) ?3 and Z = 1. Geometry optimization calculations for each compound is consistent with these observations. A comparison of the dihedral angles between mean planes of the benzene rings in the crystal with the DFT theoretical calculations and weak intermolecular hydrogen bond interactions has been included for each molecule. Electronic transitions have been predicted by DFT Molecular Orbital calculations and compared with experimental absorption spectra.

An efficient solid-phase benzoylation of phenols and alcohols was developed under microwave irradiation. A stoichiometric amount of benzoyl chloride was sufficient to carry out the reaction. This benzoylation features short reaction time, good yields, and easy workup procedures. Furthermore, the scope of the reaction was extended to prepare 3,5-dinitrobenzoyl derivatives of alcohols.

Hierarchical ZSM-5 and Beta zeolites were investigated in the synthesis of wide range of industrially important aromatic/heterocyclic ketones by Friedel-Crafts acylation and benzoylation reactions. For comparative study, conventional ZSM-5 and Beta, and amorphous mesoporous Al-MCM-41 were investigated. Hierarchical zeolites were prepared by multi-ammonium structure directing agents whereas conventional zeolites were prepared by mono-ammonium structure directing agents. Among the catalysts investigated in this study, hierarchical Beta exhibited the highest reactant conversion in the acylation and benzoylation reactions. In this study, the systematic assessment of the catalytic activity of acid catalysts for wide range of aromatic and heterocyclic compounds is shown under one umbrella. To the best of our knowledge, these reactions over hierarchical zeolites (ZSM-5 and Beta) are reported here for the first time. Structure activity relationship is explained based on the physico-chemical properties, molecular size, reactivity of reactants, and reaction mechanism. Catalysts can be easily recovered and reused with negligible loss in the catalytic activity.
