- SYNTHESE DE QUELQUES SPIRO ET SPIRO PHOTOCHROMIQUES. APPLICATION DE LA METHODOLOGIE DE LA RECHERCHE EXPERIMENTALE
-
Some spiro I and spiro II substituted by different groups were synthesized in order to evaluate their photochromic properties and to optimize the preparation of spiroheterocyclic systems.In addition, some spiro III were also prepared as reference compounds.Their physical and spectroscopic characteristics (UV, 1H and 13C) were determined.A study using the experimental design methodology allowed to point out the most important factors for improving the reaction yields. KEYWORDS: Photochromism, spirooxazines, spiropyrans, synthesis, 1H NMR, experimental design methodology.
