SYNTHESIS OF PHOTOCHROMIC DIHETARYLETHENES
Keywords:

The main methods of synthesis of dihetarylethenes are given in the review. Approaches for obtaining photochromic compounds are discussed, in which both the traditional residues of perfluorocyclopentene, maleic anhydride, and maleimide, and little-studied fragments of partially saturated or aromatic heterocycles are used as the ethenic fragment. Significant attention is paid to the X-ray structural data of open and cyclized forms of the photochromes.
