EPR-spectroscopic and quantum-chemical investigations of the fast protolytic reactions of several alkaloids

Abstract

Kinetic and thermodynamic experimental parameters for the reactions of protonation of alkaloids by spin probe 3,6-di-tert-butyl-2-oxyphenoxyl obtained by ESR spectroscopy in a toluene solution are presented. Values of various physico-chemical data obtained by quantum chemical calculations in the «Gaussian-2009» for some alkaloids, such as ionization potential, electron affinity and proton affinity have been calculated.
