Dimethylgermanium dichloride is a chemical compound from the group of organic germanium compounds .
Extraction and presentation
Dimethylgermanium dichloride can be produced in high yield analogously to the Müller-Rochow synthesis by the direct reaction of germanium with methyl chloride :
In the case of a catalytic conproportionation of tetramethylgermanium with germanium tetrachloride in a ratio of 1: 1 at 150 ° C in the bomb tube , a mixture of methylgermanium trichloride and trimethylgermanium chloride is formed , which is then converted to the desired product at an even higher temperature:
properties
Dimethylgermanium dichloride is a colorless, clear liquid with a refractive index of 1.46 and a flash point of 32 ° C.
