Complex formation between heterocyclic compounds and polynitro benzene derivativesMcEwen, Kathleen Lenore January 1953 (has links)
Complexes formed between heterocyclic compounds and polynitro benzene derivatives have been examined spectroscopically. It has been found that many complexes, when irradiated in the region of their charge-transfer absorption emit a short-lived radiation in the region of the heterocyclic triplet. There is some evidence for a radiationless transition from an excited, bonding charge-transfer state to the excited triplet level of the heterocyclic component. / Science, Faculty of / Chemistry, Department of / Graduate

The isomer distribution in the sulfonation of iodobenzeneKnight, Joseph A. 01 July 1957 (has links)
Using the isotope dilution technique, the distribution of isomers was determined when iodobenzene was sulfonated with sulfur trioxide in liquid sulfur dioxide. The active isotope was S^35. Before this distribution could be established, it was necessary to prepare the pure isomers of iodobenzenesulfonic acid. These were prepared by diazotization of the corresponding aminobenzenesulfonic acids. Since o-aminobenzenesulfonic acid was not readily available, it was necessary that it be synthesized before the diazo reactions could be carried out. Considerable work has been done on the development of a method whereby the bromobenzenesulfonic acids could be synthesized and obtained in pure form. Some work has been done in preparing the isomers of chloro-benzenesulfonic acid. The S-benzylisothiuronium derivatives of the iodo-, and amino-, and bromobenzenesulfonic acids have been prepared, purified and their melting points determined. It has been established, that when iodobenzene is sulfonated there is considerable replacement of the iodine by sulfure trioxide to form benzenesulfonic acid. When p-iodobenzenesulfonic acid was subjected to sulfonation conditions, there was essentially no exchange between the sulfonic acid group and the sulfonation agent, from which we concluded that under these conditions, there was negligible reversibility.
