Benzonitriles, benzaldehydes and benzyl alcohols of the formula I n<IMAGE>n in whichn R<1> denotes methyl or ethyl,n R<2> denotes alkyl, alkenyl, cycloalkyl, cycloalkenyl, bicycloalkyl, bicycloalkenyl or C1-C5-alkyl-substituted cycloalkyl, cycloakenyl, bicycloalkyl or bicycloalkenyl,n X denotes hydrogen, chlorine or fluorine andn Z denotes the group -CN, CHO or n<IMAGE>n where R<3> stands for hydrogen, cyano, C2-C4-alkynyl, C2-C4-alkenyl or C1-C4-alkyl,n with the proviso that R<2> does not represent the -CH2-CH=CH-B radical if B stands for hydrogen, alkyl or alkenyl and at the same time R<1> has the meaning methyl and Z has the meaning n<IMAGE>n and with the proviso that R<2> does not denote methyl or ethyl if at the same time R<1> stands for methyl and Z stands for n<IMAGE>n and finally with the proviso that R<2> does not denote methyl if at the same time R<1> stands for methyl or ethyl and Z stands for the -CN or -CHO group, and processes for their production. |
