Über Polygermane, XVIII [1] Drucksynthese der mehrfach funktionellen Digermane Ph_6-nGe₂Cl_n (n = 2, 3, 4) und von Ph₂GeCl₂ / On Polygermanes, XVIII [1] Synthesis of the Multifunctional Digermanes Ph_6-nGe₂Cl_n (n = 2, 3, 4) and of Ph₂GeCl₂ under Pressure

Abstract

<jats:p>Reaction of Ph<jats:sub>6</jats:sub>Ge<jats:sub>2</jats:sub> with liquid HCl under pressure leads to di-, tri-and tetrachloro phenyldigermanes. The yield of higher chlorinated products increases with increasing pressure. The analogous reaction of Ph<jats:sub>4</jats:sub>Ge yields Ph<jats:sub>2</jats:sub>GeCl<jats:sub>2</jats:sub> quantitatively. The Ge-Ge bond is most unstable in the case of Ph<jats:sub>3</jats:sub> Ge<jats:sub>2</jats:sub>Cl<jats:sub>3</jats:sub> both chemically and thermally. The crystal structure of Ph<jats:sub>2</jats:sub>Ge<jats:sub>2</jats:sub>Cl<jats:sub>4</jats:sub> has been determined (R = 0.057), Ge-Ge 241.3(1) pm</jats:p>
