Structure Study of the Reaction Product of Formyl-Substituted Spiropyran of 1,3-Benzoxazin-4-One Series with Malonodinitrile

Abstract

Synthesis is reported of new spiropyran based on 1,3-benzoxazin-4-one heterocycle with the vinyl-dicarbonitrile fragment at the 8′ position of the 2H-chromene part of the molecule. The structure of the isolated product is confirmed by NMR and mass spectrometry along with single crystal X-ray diffraction. Intermolecular interactions are stuided in the crystal using Mercury and CrystalExplorer program packages.
