ESR Studies of Group IV Substituted Anilines (open access)

ESR Studies of Group IV Substituted Anilines

The purpose of the investigation described herein was to investigate the degree of delocalization of the unpaired electron in ion radicals formed in the oxidation process of compounds with aromatic rings connected by means of various groups and atoms not entering the ring; then, to establish the relationship of coupling constants in radical cations with substituent σ values. The parent cation radical, in which the co-planar ion was derived from N,N-dimethylaniline, was selected in order to maximize the substituent effects on coupling constants and to obtain couplings at several positions (specifically, CH3, N, and ring protons).

Oxovanadium(IV) Complexes of Substituted N-(2-Thiophenyl)Salicylideneimine (open access)

Oxovanadium(IV) Complexes of Substituted N-(2-Thiophenyl)Salicylideneimine

In an effort to study the spectral, magnetic, and stereochemical properties of vanadyl complexes, both a new series of vanadyl complexes derived from type (VII) ligands with subnormal magnetic moment and from type (VIII) ligands with normal magnetic moment are synthesized and characterized.

Reactions of N-(Substituted) Phthalimides with n-Alkylamines (open access)

Reactions of N-(Substituted) Phthalimides with n-Alkylamines

The initial purpose of this study was to determine if steric problems would account for the difference in the products obtained in the reaction of the N-(substituted)phthalimide with low and high molecular weight amines.

Synthesis of 1-Amino-2-Hydroxycyclopentanecarboxylic Acid (open access)

Synthesis of 1-Amino-2-Hydroxycyclopentanecarboxylic Acid

This investigation involved the synthesis of 1-amino-2-hydroxycyclopentanecarboxylic acid, a potential structural analog of the natural amino acids, serine and threonine. The title compound also includes the structural features present in an established antitumor agent, cycloleucine.
