Addition Reactions of Some Aromatic Aldazines

Addition Reactions of Some Aromatic Aldazines

Date: August 1954
Creator: O'Dell, Stewart
Description: The paper explores the conclusion that the addition compound was bicyclic, and that the addition of each of the two moles of cyanic acid was dependent upon the other.

Nitration of Thiophene Analogs of DDT

Nitration of Thiophene Analogs of DDT

Date: February 1953
Creator: Buttram, Jack Rhea
Description: 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).

Barbituric Acids.  V.  5-substituted-mercapto Derivatives of 5-isoamylbarbituric Acid

Barbituric Acids. V. 5-substituted-mercapto Derivatives of 5-isoamylbarbituric Acid

Date: August 1952
Creator: Peterson, Paul Eugene
Description: Since no mention has been found in the literature of any 5-substituted mercapto-5-alkyl derivatives of barbituric acid, it was thought to be of interest to prepare a series of compounds containing sulfur attached directly to the barbituric acid nucleus. 5-substituted mercapto-5-isoamylbarbituric acids were chosen as representative of barbituric acids in which the alkyl group has a fairly high molecular weight.

A Study of the Bromination Products of Phenylmercaptoacetic Acid

A Study of the Bromination Products of Phenylmercaptoacetic Acid

Date: August 1954
Creator: Schimelpfenig, Clarence William
Description: This investigation was begun in order to determine the nature of the 104 degree melting compound prepared by Ashmore and to determine which isomers and their relative amounts are produced during bromination of phenylmercaptoacetic acid.

Hydantoins as Anticonvulsants. V. 5-Substituted-Amino Derivatives of 5-Phenylhydantoin

Hydantoins as Anticonvulsants. V. 5-Substituted-Amino Derivatives of 5-Phenylhydantoin

Date: August 1950
Creator: Jeanes, Dewey Perry
Description: This thesis describes the preparation of 5-substituted-amino derivatives of 5-phenylhydantoin. The hydantoin derivatives are to be tested for anticonvulsant activity by the Pharmacology Department of the Eli Lilly Company of Indianapolis, Indiana.

Barbituric Acids.  VII.  5-alkyl-derivatives of 5-ethoxy-barbituric Acid

Barbituric Acids. VII. 5-alkyl-derivatives of 5-ethoxy-barbituric Acid

Date: January 1955
Creator: Hyde, Harold Wayne
Description: A great deal of research has been devoted in recent years to the search for new drugs for the treatment of epilepsy and related convulsive disorders. This emphasis is occasioned by the fact that no one drug is effective for all patients, and also by the fact that the toxicity of a drug varies considerably from one patient to another. Among the most effective drugs are certain members of the hydantoin and barbituric acid series. For some time there has been in progress in this laboratory an investigation of members of these two series in which a hetro atom attached directly to the hetrocyclic nucleus is introduced into the side chain at position five of these two series.

The Synthesis of Benzo(d)pyrido(a)-benzimidazole-5,12-quinone

The Synthesis of Benzo(d)pyrido(a)-benzimidazole-5,12-quinone

Date: May 1955
Creator: Cooper, James Erwin
Description: 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 Adsorption of Radioactive Isotopes on Specific Precipitates

The Adsorption of Radioactive Isotopes on Specific Precipitates

Date: August 1954
Creator: Yarbrough, Kenneth N.
Description: The purpose of this investigation is to reveal the effects of certain factors affecting adsorption on some specific precipitates. It is hoped that the choice of precipitate types will enable extension of the information gained here to other precipitates similar to those investigated.
