The purpose of this investigation was the synthesis of some 1,4-naphthoquinones and 1,4-anthraquinones. It will be shown that some of these substituted quinones exhibit physiological properties.

A series of analogous reactions employing as a nucleus I-phenylazimidoquinone has been investigated.

This thesis describes the reactions of mercury-sensitized isopropyl alcohol when bombarded with 2537 Angstrom radiation.

This thesis describes the reactions and emission spectra of propylene under radio frequency energy radiation.

Because of the structural analogies between these compounds and several other physiologically active compounds, such as chloroamphenicol, 4,4'-diaminodiphenyl sulfone, and 2,2-bis-(p-aminophenyl)-1,1,1-trichloroethane, a more complete study of the reduction products and the sequence of catalytic reduction of N-(4-nitrophenacyl)-4-(1-hexyl)pyridinium bromide was made in this investigation.

It is the purpose of this investigation to study the chemistry of 5-(3-pyridyl)hydantoin and to compare its properties with those of 5-phenylhydantoin.

The acid which is analogous to the next member of the diphenylpolyenes, 1,4-diphenylbutadiene, is muconic acid. This acid has been chosen to be investigated in an effort to isolate all the stereoisomers of a set containing more than two isomers.

The nature and scope of this problem is to determine from the irradiation of isopropyl alcohol with 2537 A, the behavior and mechanism of the reaction, since it is known that a reaction does occur.

It is the specific purpose of this investigation to determine the difference, if any, in the amount of practical, everyday chemistry learned by the science majors as opposed to the non-science majors enrolled in general chemistry at the North Texas State College during the school year 1950-1951.

This thesis discusses the mercury-sensitized photochemical reactions of isopropyl alcohol.

This study explores the synthesis and reduction of some n-phenacylpyridines and is an investigation of various derivatives.

This thesis concerns the investigation of radioisotopes as indicators for precipitation reactions. As a precipitate forms in the presence of a radioisotope, adsorption may take place on its surface. If this adsorption changes markedly at the stoichiometric point it will be possible to use this variation as an indicator for the reaction.

Since thiophene very often yields compounds that are analogous to benzene derivatives in general physiological properties, it was decided to attempt to prepare the nitro and amino derivatives of 1,1,1-trichloro-2,2-bis-(2-thienyl)-ethane (V) as well as the nitro and amino derivatives of 2,2,3-trichloro-1,1-bis-(2-thienyl)-butane (VI).

The purpose of this investigation was to complete the study of the 5-pyridylhydantoins by resynthesizing 5-(2-pyridyl)hydantoni and investigating its properties.

In this paper, some of the work by Talbott has been repeated and other reactions of 4-picoline and pyridine N-oxides with aromatic halogen compounds have been investigated.

The purpose of this investigation then was the preparation of a series of 5-substituted-5-(1-pyrrolidyl)barbituric acids in which R would consist of alkyl groups ranging in size from methyl to amyl, and other groups such as phenyl and benzyl. These compounds are to be tested elsewhere for hypnotic and anticonvulsant activity.

The present investigation yielded an orange product upon refluxing 2-butyramido-3-chloro-1,4-naphthoquinone and 2-aminopyridine in ethanol. When this material was purified, by recrystallization from glacial acetic acid, the melting point was 306 [degrees]. This compound has been shown to be benzo(d)pyrido(a)-benzimidazole-5,12-quinone by the present investigation.

The work presented in this investigation is concerned with the chemical properties of 5-(4-pyridyl)hydantoin as compared with 5-phenylhydantoin.

The specific goal of this investigation was the determination of the self-diffusion coefficient of the divalent lead ion in a fused lead chloride system at several temperatures and the determination of the activation energy for the diffusion process.

Recent years have seen a rapid increase in the search for new compounds to be employed in the treatment of convulsions associated with epilepsy and related ailments. The properties desired are a higher degree of effectiveness and lower toxicity than those already in use. This thesis describes the effect of methylation of the 5-alkylmercapto-5-phenylhydantoins.

This investigation deals with the synthesis of 2-alkylpyridine and 2-alkylpyrazine derivatives of 2,3-dichloro-1,4-naphthoquinone. These compounds will be tested for physiological activity by Parke-Davis and Company.

This thesis is a study of 5-substituted-amino derivatives of 5-phenylhydantoin and anticonvulsant activity.

This thesis discusses hydantoins as anticonvulsants. VII. 5-Substituted-aryloxy derivatives of 5-phenylhydantoin.

This thesis investigates nitrogen derivatives of naphthoquinone.
