| titleOfInvention | Photochrome oxazine compounds and methods for their synthesis |
| abstract | FIELD: organic chemistry, chemical technology. n SUBSTANCE: invention relates to chemistry of photochrome compounds, in particular, to a method for synthesis of oxazine photochrome compounds. Invention describes two variants of synthesis of photochrome compound. The first variant involves interaction of isocyanate derivative of compound of the formula (IX): with symmetric quinone, for example, with substituted or unsubstituted 9,10-phenanthrene-9,10-dione or 9,10-1,10-phenanthroline-5,6-dione at heating but preferably at 40-120°C for 2-24 h in the presence of the catalytic amount of triphenylarsen-oxide. Another method involves interaction of azaylide compound of the formula (XIV) with above indicated symmetric quinone at heating but preferably at 60-120°C for 4-24 h. Proposed methods provide synthesis of effective photochrome compounds by simplified technology. n EFFECT: improved methods of synthesis. |
