Abstract:
A compound of the general formula ##STR8## or a salt thereof, in which m is 0 or 1;n represents an integer from 0 to 4;each R independently represents a halogen atom or a nitro, cyano, hydroxyl, alkyl, haloalkyl, alkoxy, haloalkoxy, amino, alkylamino, dialkylamino, alkoxycarbonyl, carboxyl, alkanoyl, alkylthio, alkylsulphinyl, alkylsulphonyl, carbamoyl, alkylamido, cycloalkyl, aryl or aralkyl group;R.sup.1 and R.sup.2 each independently represent an optionally substituted alkoxy group or together represent a group .dbd.O, .dbd.S or .dbd.N--OR.sup.9, where R.sup.9 represents a hydrogen atom or an optionally substituted alkyl group;R.sup.3 represents a hydroxyl group, or a group --OL where L is a leaving group or a group which in vivo is transformed into a group -L.sup.1 where L.sup.1 is a leaving group;R.sup.4 and R.sup.5, if present, each independently represent a hydrogen or halogen atom or an optionally substituted alkyl group or together with the interjacent carbon atom represent an optionally substituted cycloalkyl or cycloalkenyl group optionally containing at least one ring-silicon atom;R.sup.6 represents an optionally substituted group containing at least one silicon atom or, in the case where m is 1 and the --CR.sup.4 R.sup.5 -moiety contains at least one silicon atom, R.sup.6 may additionally represent a hydrogen atom or an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, alkoxy, alkenyloxy, alkynyloxy, cycloalkoxy, cycloalkenyloxy or aryloxy group; andR.sup.7 and R.sup.8 independently represent an optionally substituted alkoxy group or together represent a group .dbd.O, .dbd.S or .dbd.N--OR.sup.9, where R.sup.9 is as previously defined;wherein, when R.sup.6 represents an optionally substituted group containing at least one silicon atom, at least one of the silicon atoms of R.sup.6 is not directly attached to a carbocylic ring.
