| titleOfInvention | Preparation of benzylidene compounds |
| abstract | A process for the preparation of a benzylidene compound of the formula ##STR1## in which R 1 is hydrogen or one or two substituents independently selected from the group consisting of nitro, cyano, halogen, SO 3 H, alkyl, alkoxy and fluorinated alkyl, each with 1 to 4 C atoms and two or three fluorine substituents, and n R 3 is alkyl with 1 to 10 C atoms, which is optionally interrupted by an oxygen in the chain or is optionally substituted by fluorine, chlorine, hydroxyl or a methylbenzylamine group, comprising reacting an acetal of the formula ##STR2## in which R 2 each independently is alkyl with 1 to 6 C atoms, which is optionally substituted by phenyl, or the two radicals R 2 conjointly form an alkylene radical with 1-6 C atoms, n with a β-ketocarboxylic acid ester of the formula n n CH.sub.3 CO--CH.sub.2 --COOR.sup.3 n n in the presence of an acid at a temperature between about 40° and 120°. |
