| titleOfInvention | PROCESS FOR PREPARING SUBSTITUTED VINYL-CYCLOPROPANARBONIC ACIDBENZYL ESTERS. |
| abstract | A process for the preparation of a substituted vinyl-cyclopropanecarboxylic acid ester of the formula <IMAGE> in which R1 and R2 each independently is alkyl with 1-4 carbon atoms or halogen, R3 is halogen, phenoxy or phenoxy substituted by alkyl with 1-4 carbon atoms or by halogen, R4 is halogen or methyl, and n is 0, 1, 2, 3 or 4, comprising saponifying with alkali an ester of the formula <IMAGE> in which R5 is alkyl with 1-4 carbon atoms, thereby to replace R5 by an alkaline salt group, and directly reacting such salt without intermediate purification with a benzyl chloride of the formula <IMAGE> Advantageously the benzyl chloride is obtained by the gas-phase photochlorination of a compound of the formula <IMAGE> (IV), the chlorination proceeding to about 25 to 75%, and the chlorination mass being employed directly without isolation. |
