ELECTRON-EXCESSIVE SYSTEMS - STUDY OF THE CHARACTER OF SPECTRAL PHENOMENA OF WEAK MAGNETIC-FIELDS AND CONFORMATIONS OF ACETYLENIC AMIDOGLYCOLS

The synthesis was carried out of model acetylenic amidoglycols. Conclu sions were made from an analysis of the PMR spectra on the possibility of transfer of magnetic fields through an electron-excessive acetylen ic bond and on conformation of amidoglycols. The low value of the obse rved nonequivalency of the germinal methyl groups, separated from the asymmetric center by an acetylenic bond, in the PMR spectra is explain ed by characteristic features of the electronic structure and conforma tional rigidity of the acetylenic bond.
