A diarylethene compound reversibly convertible under photochromic and electrochromic conditions between a ring-open isomer of Formula (1A) and a ring-closed isomer of Formula (IB) wherein R5 is a substituted phenyl ring and Re is a substituted thiophene ring is provided. The photochromic-electrochromic diarylethene compound of Formula (1A)/(1B) have improved photochromic, electrochromic or photochromic and electrochromic properties, and is useful to provide variation of the light transmission properties of optical filters. The compound also possesses improved solubility making it suitable for incorporation in commercial products..

Abstract The oxidation of organiccompounds by potassium permanganate supported on Montmorillonite K10 has been studied under solvent‐free conditions and the results compared with those from corresponding reactions where the reductants are dissolved in methylene chloride. Under both sets of conditions, primary benzylic and secondary alcohols are converted to aldehydes and ketones respectively, sulfides

The present invention relates to a process facilitating the regeneration of a catalyst based on a zeolite, employed in an acylation reaction.
Another subject of the invention is a process for acylation of an aromatic ether, comprising, in a preferred alternative form, an additional stage of regeneration of the catalyst.
The process of the invention, which makes it possible to regenerate more easily a catalyst based on a zeolite, employed in an acylation reaction, is characterized in that the zeolite is modified by addition of an effective quantity of at least one metallic element M chosen from the elements of group 8 of the Periodic Classification of the elements.
