Dicondensed indolinobenzospiropyrans as precursors of thermo- and photochromic spiropyrans. Part II Assignment of (1)H and (13)C NMR spectra

Dicondensed indolinobenzospiropyrans as precursors of thermo- and photochromic spiropyrans. Part II : Assignment of (1)H and (13)C NMR spectra

The (1)H and (13)C NMR spectra of dicondensed indolinobenzospiropyrans as precursors of thermo- and photochromic spiropyrans, DC1-DC5, were completely assigned. Especially, the (1)H assignment and coupling characteristics of the diastereotopic protons at the carbon-3 position of the benzopyran rings...
