Abstract
The effect of substituents in position 6 on the positions of the signals of the carbon atoms in the 13C NMR spectra of substituted 1,2,3,4-tetrahydro-5,10-phenazine N,N′-dioxides has been analyzed, increments of substituents have been found, and a scheme has been proposed for the calculation of the chemical shifts of carbon atoms in the 13C NMR spectra of 6(7)-R-quinoxaline N,N′-dioxides.
