New Photochromic Salt Spiropyrans of Indoline Series

Doklady Chemistry, 2019
The synthesis and study of the structure and photochromic properties of the new salt spiropyrans of the indoline series containing chlorine and bromine atoms as a substituent at the 6' position in 2H-chromene moiety are presented. The structure of the obtained compounds was confirmed by NMR 1H spectroscopy and X-ray diffraction analysis.
