Abstract	Elektrophile Substitutionen donorsubstituierter Aryltrimethylsilane (z.B. Alkylphenyl- oder Aminophenyltrimethylsilane) lassen sich nicht durch Nucleophile katalysieren. Gerade diese Verbindungen reagieren aber mit Elektrophilen in Gegenwart eines Friedel-Crafts-Katalysators besonders gut; hierbei ist jedoch die dirigierende Wirkung der Substituenten oft starker als die Neigung zur ipso-Substitution der Trimethylsilylgruppe, so das haufig "normale" H-Substitution stattfindet. Der elektronenziehende und damit anionenstabilisierende Einflus der Tricarbonylchrom-Gruppe in Aren(tricarbony1)chrom-Komplexen sowie deren praparative Verwendung ist beschrieben.
