Technology Process of Oxogermane

There total 5 articles about Oxogermane 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:

germanium (7440-56-4) + germanium dioxide → germanium monoxide (20619-16-3)

Guidance literature:

In neat (no solvent); mixture evaporated in a Al2O3 crucible within a tantalum tube heated to900°C;

DOI:10.1016/0022-2852(85)90218-8

Reference yield:

(O(CHCH2)2GeO(CCH3CH2)2) (172654-86-3) → germanium monoxide (20619-16-3) + germanium dioxide

Guidance literature:

In solid matrix; pyrolysis of Ge-compd. at 800 - 900°C at 10 E-3 torr; not isolated; product is captured in a frozen Ar-matrix; detn. by IR spectroscopy;

DOI:10.1007/BF00961022

Reference yield:

germane (7782-65-2) + ozone (10028-15-6) → germanium(II) oxide + germanium acid + germanone (20619-16-3) + hydroxygermylene peroxo adduct (125686-67-1) + germanol

Guidance literature:

byproducts: O2, H2; Irradiation (UV/VIS); codeposition of germane/Ar and ozone/Ar at 14-18 K for 10 h, exposure of matrix to irradiation from high-pressure mercury arc lamp (first range 590-1000 nm, then 380-1000 nm, 290-1000 nm and full arc, 1 h for each range); not isolated, detected by IR;
