A Three Part Research Report: The Synthesis of Potential Insecticides, N-(4-Heteroaryloxybenzoyl)-N'-(2,4-Dichlorobenzoyl) Hydrazines: A Reinvestigation of Hexamethylphosphoramide with Ketoximes; Regioselective Fluoralkoxylation and Polyfluoroalkoxylation of Activated Dihalobenzenes and DihaloheterocyclesDeCrescenzo, Gary A. 01 January 1984 (has links) (PDF)
This report discusses research in three areas of organic synthesis: The synthesis of potential insecticides; the reinvestigation of the reaction of hexamethylphosphoramide with ketoximes; and the regioselective fluoroalkoxylation and polyfluoroalkoxylation of activated dihalobenzenes and dihaloheterocycles. In Part I, a series of N-(4-heteroaryloxybenzoyl)-N'-(2, 3-dichlorobenzoyl) hydrazines are synthesized, and attempts at cyclic dehydration to the corresponding 2, 5-disubstituted-1, 3, 4-oxadiazoles are discussed. In Part II, the synthesis of N, N-dimethyl-N'-aryl amidines by the reaction of aryl alkyl and diaryl ketoximes with HMPA is discussed. In Part III, a series of activated dihalobenzenes and dihaloheterocycles are reacted with sodium trifluoroethoxide to study the possibility of regioselective fluoroalkoxylation and polyfluoroalkoxylation of these activated substances.

Electrophoretic distribution of glycoproteins of bovine, avian and human blood sera.Gaunce, Alan Peter. January 1965 (has links)
In recent years the study of serum glycoproteins has advanced rapidly. Much of this interest in serum protein-carbohydrate complexes has been inspired by findings that many physiological and pathological conditions are associated with elevated serum protein bound carbohydrates. Paper electrophoFesis has been used in many studies of the serum glycoproteins of the human and experimental animals. Reports on the electrophoretic distribution of serum glycoproteins in most animals, however, are lacking. [...]
