One-pot synthesis and the structure study of a new indoline spiropyran with cationic substituent
One-pot synthesis and the structure study of a new salt spiropyran of indoline series containing 2H-chromenic vinyl-3H-indolium fragment as a substituent at the position 8 are described. The structure was confirmed by the method of NMR 1H and 13C spectroscopy, IR and high-resolution mass spectrometry. The single crystals of the compound were investigated by X-ray analysis. The structure was compared with the previously known isostructural analogue [10].
