Technology Process of Ph₃GeGePh₂GePh₃

There total 9 articles about Ph₃GeGePh₂GePh₃ which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 91.0%

triphenyl germyllithium (3839-32-5) + dichlorodiphenylgermane (1613-66-7) → Ph3GeGePh2GePh3 (81483-61-6)

Guidance literature:

In diethyl ether; Ph3GeLi (prepd. from Ph3GeH and BuLi) was added to Ph2GeCl2 in ether under Ar, mixt. was heated under reflux (35°C) for 1 h; reaction mixt. was hydrolyzed, extd. with ether. ext. dried over Na2SO4, concd. under reduced pressure, residue was recrystd.;
