Gorkunenko O. NMR spectroscopy of molecules with structurally rigid frameworks and groups with slow internal rotation

The dissertation develops fragmentary model of shielding scheme NMR-1Н and 13С interpretation in the decision of problems of a spatial structure, conformation and stereoisomeric structure of structurally rigid molecules and conformatively labile structures. Mechanisms of complication of a spectral picture in NMR-1Н and 13С spectra of amides and hydrazides of carboxylic acids under influence of conformation transitions in several amid fragments were defined. The scheme of estimation of difference in electronic density of NH proton at change of conformation in amid fragment was offered. The offered scheme based in using of constants of conformation balance. By the methods of NMR spectroscopy was shown, that in reaction of endo-dicyclopentadiene with dichlorcarbene the product of connection is formed only on one of two double bonds. The structure of monoadduct of endo-dicyclopentadiene and dichlorcarbene as a product of connection on a double bond in fifth member cycle with trans-orientation of norborneneand cyclopropane framework was established.
