    Description / Table of Contents: Preparation of Aryl- and Heteroaryl-trimethylsilanes - Scope of “in situ” Grignard SynthesisAryl and heteroaryl halides react upon heating with magnesium and chlorotrimethylsilane in hexamethyl phosphoric triamide to give aryl and heteroaryl trimethylsilanes in good yields. The advantage of the “in situ” Grignard synthesis over other methods is demonstrated. The scope and limit of this synthesis is investigated for variously substituted aryl compounds and various hetero-cyclic systems.
    Notes: Aryl- und Heteroarylhalogenide reagieren beim Erwärmen mit Magnesium und Chlortrimethylsilan in Hexamethylphoshorsäuretriamid in guten Ausbeuten zu Aryl- und Heteroaryltrimethylsilanen. Die Vorteile dieser „in-situ“-Grignard-Synthese gegenüber anderen Verfahren werden be-schrieben, Anwendungsbreite und Grenzen dieser Methode bei verschieden substituierten Aroma-ten sowie unterschiedlichen Heterocyclen untersucht.
