Summary
-
1.
It is pointed out that the relative amounts of halomethyl- and halodimethylgermanes obtained in their direct synthesis from germanium and CH3X are greatly affected by the amount of copper used.
-
2.
It is shown that Rochow's conclusions regarding the properties of chlorotrimethylgermane are incorrect.
-
3.
It is shown that it is possible to prepare dibromodimethylgermane, bromotrimethylgermane, and trialkyl(iodomethyl)germanes from the corresponding chloro compounds by exchange reactions with MgClBr and MgCII.
-
4.
It is shown that chloro(chloromethyl)germanes can be prepared by the photochemical chlorination of organogermanium compounds with application of the principle of removal of reaction products from the chlorination zone.
