Abstract: Styrenes of the general formula are obtained from a corresponding hydroxyaldehyde, which is reacted with at least n mol of a vinyl ether of the formula CF2=CFOR to give the perfluorinated aldehyde and subsequently with a methylenetriarylphosphonium halide, in each case in the presence of inert, aprotic solvents and various bases, to give compounds (I). The styrenes (I) are used for the preparation of polymers which serve as support materials for chromatographic processes, as materials for optic systems, as resists, as mouldings and adhesives.

Abstract: Alkyl(C1-C3) nitrobenzoates are prepared by reacting the nitrobenzoic acid to be esterified with an excess of about 300 to about 600 mol % of a C1-C3-alkanol in a solvent which is inert towards the starting compounds and the reaction product in the presence of a polyfluoroalkanesulphonic acid of the general formula (1> Y(CnF2n)SO3H (1> in which Y denotes a hydrogen or fluorine atom, with the proviso that if Y is H this hydrogen atom is in the beta -position relative to the sulpho group, or the hydrate thereof as catalyst in an amount of about 0.1 to about 20 mol %, relative to the nitrobenzoic acid used, at temperatures of about 60 to about 120 DEG C.

Abstract: The invention relates to a process for the preparation of compounds of the formula I and salts or acid addition compounds thereof (I) in which R denotes hydrogen, (halogenated) alkyl with the exception of CF3, a (substituted) aromatic radical, (substituted) heteroaryl, (substituted) phenoxy, (substituted) phenylthio, (substituted) phenylamino, halogen, hydroxyl, alkoxy, mercapto, (halogenated) cycloalkyl, alkylmercapto, amino, monoalkylamino or dialkylamino, R1 denotes (substituted alkyl, (substituted) phenyl or naphthyl, alkenyl, alkinyl, cycloalkyl, (substituted) benzyl or heteroaryl, and X denotes oxygen or sulfur, which comprises reacting a nitrile of the formula II with a compound of the formula III R-C 3BOND N (II) R1-XH (III) in the presence of anhydrous hydrofluoric acid, a perfluoroalkanecarboxylic acid, a perfluoralkanesulfonic acid or a perfluorinated ion exchanger containing sulfonic acids, and converting the resulting salts of the formula I, if appropriate by the addition of bases, into the free imidates of the formula I and, if approximate, converting the latter subsequently into further salts or acid addition compounds. The invention also relates to the new compounds of the formula I in which R1 denotes a (substituted) phenyl radical and R and X have the meanings mentioned. The compounds of the formula I are valuable intermediate products in the preparation of plant protection agents and pharmaceuticals.
