摘要

Compounds of the general formula (I): (See formula) in which each R is chosen separately from a halogen atom; a cyano group; a nitro group; a carboxy group; an optionally halogenated (C1 to C18) alkoxycarbonyl group; a Ra-CO-NH- or RaRbN-CO- [group in which Ra and Rb optionally separately represent optionally halogenated (C1 to C18) alkyl; a hydrogen atom; aryl (C6 to C10) or aryl (C6 to C10) - (C1 to C5) alkyl (where the aryl parts are optionally substituted by a halogen atom, by an optionally halogenated (C1 to C5) alkyl group or by an alkoxy group (C1 to C5) optionally halogenated); (C3 to C12) cycloalkyl optionally substituted by a halogen atom, by an optionally halogenated (C1 to C5) alkyl group or by an optionally halogenated (C1 to C5) alkoxy group]; an optionally halogenated (C1 to C18) alkyl group; optionally halogenated (C1 to C18) alkoxy; and aryl (C6 to C10), aryl (C6 to C10) - alkyl (C1 to C5), aryloxy (C6 to C10), cycloalkyl (C3 to C12), cycloalkenyl (C3 to C12), cycloalkyloxy (C3 to C12), cycloalkenyloxy (C3 to C12); aryloxycarbonyl (C6 to C10) or arylcarbonyl (C6 to C10); wherein the aryl, cycloalkyl and cycloalkenyl parts are optionally substituted by a halogen atom, by an optionally halogenated (C1 to C5) alkyl or by an optionally halogenated (C1 to C5) alkoxy; R can be located at position 6, 7, 8 or 9 in the benzoxepine structure; p represents 0, 1, 2, 3 or 4; as well as its geometric isomers and stereoisomers of the compounds of the formula (I) or mixtures thereof.
