摘要:
Process for preparing aromatic olefins of the formula (1) ##STR1## in which R.sup.1 -R.sup.3 are hydrogen, alkyl (C.sub.1 -C.sub.8) , alkoxy-(C.sub.1 -C.sub.5), phenyl, fluorine, chlorine, bromine, --OH, --NO.sub.2, --CN, --CHO, --COalkyl(C.sub.1 -C.sub.4) , --COphenyl, --COOalkyl (C.sub.1 -C.sub.4) , --OCOalkyl(C.sub.1 -C.sub.4), --NHCOalkyl(C.sub.1 -C.sub.4) , --CF.sub.3, --NH.sub.2, --NH--alkyl(C.sub.1 -C.sub.4) or --N(alkyl(C.sub.1 -C.sub.4)).sub.2 and R.sup.4 is hydrogen, alkyl(C.sub.1 -C.sub.8), phenyl, fluorine, chlorine, bromine, --OH, --NO.sub.2, --CN, --CHO or --OCOalkyl (C.sub.1 -C.sub.4) , and X is, inter alia, alkenyl(C.sub.2 -C.sub.12) or cycloalkenyl(C.sub.4 -C.sub.8) or the group ##STR2## in which R.sup.5 and R.sup.6 are, independently of one another, hydrogen or methyl, and Y is --phenyl, --CN, --COOH, --COOalkyl(C.sub.1 -C.sub.12), --COOphenyl, ##STR3## --CON (phenyl).sub.2, --COalkyl(C.sub.1 -C.sub.12), --COphenyl, --Oalkyl(C.sub.1 -C.sub.12) , --Ophenyl or the radical ##STR4## in which R.sup.1 -R.sup.4 are as defined above, by reacting an aryldiazonium salt of the formula (2) ##STR5## in which R.sup.1 -R.sup.4 are as defined and Z is the equivalent of an anion of an acid having a pK.sub.a of less than 7, with an olefin of the formula (3)HX (3)
