The Direct Synthesis of Organogermanium Trihalides

摘要

n-Alkyl chlorides above propyl chloride react with germanium in the presence of copper as catalyst at 375-425C to yield n- and i-alkylgermanium trihalides. The by-products of this reaction are the corresponding n- and i-alkenes. Chlorocyclohexane shows a rather poor yield. Phenyl germanium trichloride can be prepared by the action of germanium tetrachloride and phenyl chloride on germanium under similar conditions. (Author)
