Abstract: Esters of arylacetic acids, more particularly lower alcohol esters of arylacetic acids, including those substituted on the methylene group, are prepared by rearrangement of the corresponding alpha-halo-alkylarylketones with Ag compounds in lower alcohols and in an acid medium. From the alkyl esters so prepared, their respective free acids can be obtained, if desired, by various means such as hydrolysis or the shift with mineral acids of the alkaline salts prepared by reaction with alkali, etc.

Abstract: The present invention relates to a new class of "bismethinic" pigments having the following formula: (I) wherein: A represents a phenyl, diphenyl, naphthilic or anthracenic group, that may be substituted with groups selected from halogens, alkyl groups having from 1 to 4 carbon atoms and alkoxyl groups having from 1 to 4 atoms; B represents a phenyl, a naphthyl, anthraquinone or heterocyclic group such as benzothiazol, pyrazol, pyridine, isoindazol, benzimidazolone, that may be substituted with groups selected from hydroxyl, halogens, alkyl groups having from 1 to 4 carbon atoms, alkoxyl groups having from 1 to 4 carbon atoms, carboxylic, carbamoylic, benzamidic, acylaminic, benzoylaminic, dialkylaminic groups having from 1 to 4 carbon atoms in the alkyl radical, ureidic, thioureidic groups and arylazo groups, that may also be substituted in their aryl group with alkyl and/or alkoxyl groups having up to 4 carbon atoms and halogens. The invention also relates to the preparation of the pigments of formula (I) and their use.
