## Abstract Heats of formation and net atomic charges of some 120 structures involving substituted phenols, anilines, and benzoic acids and the corresponding anions were calculated by MNDO, AM1, and PM3 semiempirical methods. The gas phase acidities of substituted phenols and anilines and the net a
4,4Π-(1,4-Phenylenedioxy)dibenzoic acid as well as the 2-methyl-, 2-tertbutyl-, or 2-phenyl-substituted derivatives of this dicarboxylic acid were synthesized in two main steps from p-fluorobenzonitrile and hydroquinone or its methyl-, tert-butyl-, or phenyl-substituted derivatives. Polyhydrazides a
## Abstract A chiral stationary phase (CSP **1**) based on (+)β(18βcrownβ6)β2,3,11,12βtetracarboxylic acid was applied to the resolution of __N__β(substituted benzoyl)βΞ±βamino acid amides and esters. __N__β(Substituted benzoyl)βΞ±βamino acid amides were well resolved using a mixture of acetic acidβt
