Technology Process of Chlorotrimethylgermane

There total 57 articles about Chlorotrimethylgermane 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: 100.0%

tetramethylsilane (75-76-3) + germaniumtetrachloride (10038-98-9) → chloro-trimethyl-silane (75-77-4) + chlorotrimethylgermane (1529-47-1) + dimethylsilicon dichloride (75-78-5,30107-43-8)

Guidance literature:

aluminium bromide; In neat (no solvent); molar ratio Me4Si/GeCl4 = 2/1, at 200°C for 15 h, cooled; NMR, mass spectra, chromy.;

DOI:10.1021/om00125a024

Reference yield: 93.0%

germanium (7440-56-4) + methylene chloride (74-87-3) → chlorotrimethylgermane (1529-47-1) + methyltrichlorogermane (993-10-2) + dichlorodimethylgermanium (1529-48-2)

Guidance literature:

With copper; In neat (no solvent); mixing Ge and Cu, heating this contact mass in a reactor (350°C, 2 h) in a stream of purified N2, raising temp. to 425+/-5°C, replacing N2 by CH3Cl, getting a liq. product after 15 min in the ice-cooled receiver flask, react. time: 14 h; bubbling N2 through the resulting product mixture for 15 min to remove dissolved CH3Cl, detn. by (1)H NMR spectroscopy;

Reference yield: 91.0%

tetramethylsilane (75-76-3) + germaniumtetrachloride (10038-98-9) → chloro-trimethyl-silane (75-77-4) + chlorotrimethylgermane (1529-47-1) + tetramethylgermane (865-52-1)

Guidance literature:

aluminium bromide; In neat (no solvent); molar ratio Me4Si/GeCl4 = 2/1, at 180°C for 2.75 h, cooled; NMR, mass spectra, chromy.;
