PROCESS FOR THE PREPARATION OF 4- FLUOROALKOXYCINNAMONITRILES

Process for the preparation of 4-fluoroalkoxycinnamo-nitriles. The invention relates to a process for the preparation of fluoroalkoxycinnamonitriles of the formula (I) ( I ) in which n is 1 to 8 and m is 1 to 17, where m ? 2n+1, by reacting 4-fluorobenzaldehyde with a fluoroalkanol of the formula (I...

Zusammenfassung:Process for the preparation of 4-fluoroalkoxycinnamo-nitriles. The invention relates to a process for the preparation of fluoroalkoxycinnamonitriles of the formula (I) ( I ) in which n is 1 to 8 and m is 1 to 17, where m ? 2n+1, by reacting 4-fluorobenzaldehyde with a fluoroalkanol of the formula (II) H2n+1-mFmCnO-H (II) in which m and n are as defined above, in the presence of a base and, if appropriate, a solvent, and reacting the resulting 4-fluoroalkoxybenzaldehyde with cyanoacetic acid or an alkyl cyanoacetate in the presence of a base and, if appropriate, a solvent.
