Cycloadditions of Dichloroketene

Cycloadditions of Dichloroketene

Date: June 1967
Creator: Waters, Oralee Hurst
Description: An investigation of the cycloaddition behavior of dichloroketene with various types of olefins seemed in order to determine if dichloroketene behaved similarly to dialkylketenes. It was anticipated that a study of this type would indicate the reactivity of dichloroketene to various types of olefinic compounds and thus establish if the ease of cycloaddition with dichloroketene parallels the nucleophilicity of the olefin as it does in dialkylketenes.

The Electrochemical Properties of the Mercury/lithium Nitrate-potassium Nitrate Eutectic Interface

The Electrochemical Properties of the Mercury/lithium Nitrate-potassium Nitrate Eutectic Interface

Date: August 1968
Creator: Flinn, David R.
Description: The original purpose of this investigation was to attempt to apply the coulostatic method directly to a molten salt system. The inability to duplicate the reported capacity data for this system resulted in an investigation of the probable cause of this discrepancy between the data obtained by these different methods (14, 15).

Infrared Studies of Anions of Barbituric Acids

Infrared Studies of Anions of Barbituric Acids

Date: August 1960
Creator: Barnhart, Richard Lee
Description: As long ago as 1881, it was realized that a functional group of atoms in a molecule would cause an absorption band to appear at a particular frequency in the infrared spectrum of the molecule. In more recent years, the concept of characteristic group frequencies has become firmly established and has resulted in the present widespread use of infrared spectroscopy. There appear to have been relatively few studies of infrared absorption of organic acids as compared with their salts.

An Infrared Study of some Ω-Phenyl and Ω-Benzoyl Alkanoic Acids

An Infrared Study of some Ω-Phenyl and Ω-Benzoyl Alkanoic Acids

Date: August 1963
Creator: Chanslor, Robert Janes
Description: There is no available information in the literature on interaction between carboxyl hydrogen and ω-phenyl groups. Consequently, it was of interest to seek such interactions. Some form of interaction is evident from the study of the spectra of some phenylalkanoic acids and benzoyalkanoic acids.

Magnetic Exchange in Oxovanadium(IV) Complexes with N-Salicylideneamino Acids

Magnetic Exchange in Oxovanadium(IV) Complexes with N-Salicylideneamino Acids

Date: January 1968
Creator: Hu, James Hung-Jen
Description: Copper(II) and oxovanadium(IV) ions resemble one another magnetically in having one unpaired electron in their complexes irrespective of their geometrical structures and bond types involved. Copper(II) complexes with antiferromagnetic exchange are well known. On the contrary, antiferromagnetic exchange in oxovanadium(IV) complexes is rather new and not well established. Very few oxovanadium(IV) complexes have been reported to have this anomalous magnetic property. In the investigation of the magnetic properties of oxovanadium(IV) complexes, we have successfully prepared two series of new oxovanadium(IV) complexes with N-salicylideneamino acids.

Nuclear Magnetic Resonance Spectra of Some 1,2,4-triazoles

Nuclear Magnetic Resonance Spectra of Some 1,2,4-triazoles

Date: January 1967
Creator: Creagh, Linda Truitt
Description: In the work undertaken here, NMR has been used to ascertain the structure of some 1,2,4-triazoles. The investigation provides information concerning the structure of potentially tautomeric triazoles such as hydroxy- and aminotriazole. Connected with this aspect of triazole chemistry is the larger problem of mesohydric tautomerism. The present study also yields information for a comparison of substituent effects in triazoles, N-heteroaromatic substances and benzene.
