Investigation of the structure of substituted 3H, 6H-6-sila-3-azaaceanthrylenes by PMR spectroscopy

The structure of substituted 3H,6H-6-sila-3-azaaceanthrylenes was confirmed as a result of an analysis of the PMR spectra and by the spectra at 360 MHz. Computer analysis of the ABCD spectrum of the phenylene protons demonstrated the characteristic nature of the spin-spin coupling constants (SSCC) in the indicated series.
