Metalation Reactions. XII. One-pot Synthesis of 1,3-Benzothiasiloles, 1,3-Benzothiastannoles and 1,3-Benzodithioles

Abstract

The dilithiated species of (methy1thio)benzene reacts with various dichlorosilanes, dichlorostannanes and sulfur chloride yielding derivatives of 1.3-benzothiasilole, 1.3-benzothiastannole and 1,3-benzodithiole respectively.By reaction with tetrachlorosilane a spirocyclic silicon compound is obtained.A description of the synthesis is given.The structures of the reaction products were determined by elemental and spectroscopic analyses.
