Beryllium methoxide

Reaction of beryllium dialkyls with an excess of alcohol yields the alkoxides Be OR)2. The methoxide and ethoxide are insoluble and... 

The advantage of this method over the others described in the preceding sections is that the lithium chloride is soluble in methanol, making the separation of insoluble methoxides easily possible. The method was later extended by other workers for the preparation of methoxides of beryllium, " lanthanum,uranium, neptunium, vanadium, iron, ° and copper. ... 

Similar to beryllium n-diaUcoxides, zinc dialkoxides are also insoluble and nonvolatile compounds. " " The alkylzinc alkoxides are, however, less polymeric and exhibit higher volatility. For example, the cryoscopic molecular weight determination in benzene indicates that methylzinc methoxide and terf-butoxide as well as ethylzinc tert-butoxide are tetrameric" with sublimation temperatures of 60, 95, and 105°C, respectively under 0.0001 mm pressure. ...
