Abstract
Abstract Dimethylsilyl-substituted benzoyl chlorides, in particular 4-(dimethylsilyl)benzoyl chloride, are prepared in a 3-step process by reacting dihalo aromatics in the 1st step with dimethylchlorosilane and magnesium according to Grignard, reacting the halophenyldimethylsilanes thus obtainable in a 2nd step with magnesium in the presence of carbon dioxide with the formation of the corresponding dimethylsilyl-substituted benzoic acids, which are then converted in the 3rd step to the dimethylsilyl-substituted benzoyl chlorides using halogenating agents, such as thionyl chloride.
