Abstract

A trifluoromethyl-phenoxy-phenyl-silicon compound is disclosed of the general formula ##STR1## in which X.sup.1 and X.sup.2 independently of each other represent a hydrogen, fluorine, chlorine, bromine or iodine atom, PA1 Y represents a hydrogen or halogen atom or a cyano or nitro group, PA1 n is 0 or 1, PA1 m is 0, 1, 2 or 3, PA1 p is 0, 1, 2 or 3, PA1 X.sup.3 and X.sup.4 independently of each other represent oxygen or a --CO--O-- group, PA1 R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently of one another represent a hydrogen atom or a C.sub.1 to C.sub.5 alkyl group, PA1 R.sup.5 and R.sup.6 independently of each other represent a C.sub.1 to C.sub.5 alkyl group, and PA1 R.sup.7 represents a C.sub.1 to C.sub.5 alkyl or hydroxyl group, a chlorine, bromine, or iodine atom or a C.sub.2 to C.sub.5 alkenoxy, C.sub.2 to C.sub.5 alkinoxy, PA1 C.sub.1 to C.sub.5 alkylthio, C.sub.2 to C.sub.5 alkenyl-thio or C.sub.2 to C.sub.5 alkinyl-thio group or a C.sub.1 to C.sub.5 alkoxy group which is straight-chain or branched and optionally substituted by fluorine, chlorine, bromine, iodine, C.sub.1 to C.sub.5 alkoxy and/or C.sub.1 to C.sub.5 alkylthio, or represents a radical of the general formul…
