Tetramethylgermane Usage And Synthesis

Chemical Properties

clear colorless to slightly yellow liquid

Uses

Employed as a Chemical Vapor Deposition (CVD) precursor to germanium oxide thin films.

Uses

CVD precursor to germanium oxide thin films.

reaction suitability

core: germanium

Synthesis

Tetramethylgermane can be made by reacting tetrachlorogermane and methylmagnesium chloride.

It is also feasible to use dimethylzinc or dimethylcadmium instead of methylmagnesium chloride.
