Abstract

Inventia se refera la un procedeu pentru prepararea unor N-halometil-acilamide, cu formula generala I: (vezi formula) în care x reprezinta un atom de hidrogen, un atom de halogen, un radical alchil sau haloalchil cu 1...6 atomi de carbon, un radical cicloalchil cu 3...7 atomi de carbon, un radical fenil sau benzil, sau oricere din numiti radicali substituitti printr-un atom de halogen, o grupa NO2, CF3, alchil sau alcoxi cu 1...6 atomi de carbon, fenil, benzil, simbolul R reprezinta un radical aciclic 1-alchen-1-il, avînd pîna la 10 atomi de carbon, un radical cicloalchil sau 1-cicloalchen-1-il, avînd pîna la 7 atomi de carbon, un radical fenil sau numitii radicasi cicloalchil, 1-cicloalchen-1-il sau fenil substituiti cu unul sau mai multi radicali alchil cu 1...6 atomi de carbon, alcoxi cu 1...6 atomi de carbon, alcoxialchil cu 1...6 atomi de carbon, alcoxialchil cu 1...6 atomi de carbon, alchenil cu 2...4 atomi de carbon, alcheniloxi cu 3...4 atomi de carbon, NO2, trifluormetil sau halogen, R2 reprezinta un atom de brom sau clor, si anume, un compus cu formula generala II: (vezi formula) în care X si R au semnificatiile sus-mentionate, iar R1 reprezinta un radical alchil cu pîna la 10 atomi de carbon sau un astfel de radical substituit cu halogen sau grupari alcoxi sau alcoxialchil cu 1...8 atomi de carbon , reactioneaza cu clorura sau bromura de tionil, la o temperatura cuprinsa între 0 si 100 degree C, în prezenta de acid Lewis, ales dintre acid fluorhidric, triflorura de bor, triclorura de aluminiu, trifluorura de bor eterata.The invention relates to a process for the preparation of N-halomethyl-acylamides of the general formula I wherein x represents a hydrogen atom, a halogen atom, a C1-6 alkyl or haloalkyl radical carbon, a cycloalkyl radical of 3-7 carbon atoms, a phenyl or benzyl radical, or any of said radicals substituted by a halogen atom, a group of NO2, CF3, alkyl or alkoxy of 1-6 phenyl, benzyl, the symbol R represents a 1-alkenyl-1-yl acyclic radical having up to 10 carbon atoms, a cycloalkyl or 1-cycloalken-1-yl radical having up to 7 carbon atoms, a phenyl radical or radicals such as cycloalkyl, 1-cycloalken-1-yl or phenyl substituted by one or more alkyl radicals of 1 to 6 carbon atoms, alkoxy of 1-6 carbon atoms, C 1-6 alkyl, C 1-6 alkoxyalkyl, C 2-4 alkenyl, C 3-4 alkenyl, N 2, trifluoromethyl or halogen, R 2 represents a bromine or chlorine atom, i.e., a compound of the general formula II wherein X and R are as defined above and R 1 represents an alkyl radical of up to 10 carbon atoms or such a halogen-substituted or alkoxy or alkoxyalkyl group of 1 to 8 carbon atoms is reacted with thionyl chloride or bromide at a temperature of between 0 and 100 ° C in the presence of Lewis acid selected from hydrofluoric acid, boron trifloride, aluminum trichloride, boron trifluoride etherate.
