Preparation of Tetramethylstannane: it can be prepared by methylmagnesium iodide and tin tetrachloride, which is synthesized by reacting tin metal with chlorine gas. The equation is as follows: 4CH₃MgI + SnCl₄ → (CH₃)₄Sn + 4MgICl.

Uses of Tetramethylstannane: its liquid is useful for transition-metal mediated conversion of acid chlorides to methyl ketones and aryl halides to aryl methyl ketones. It can react with SnMe4 to get Me3SnCl at temperatures between 100 °C and 200 °C. The equation is as follows: SnCl₄ + 3SnMe₄ → 4 Me₃SnCl. In addition, it can react with 1-iodo-4-nitro-benzeneto give 1-methyl-4-nitro-benzene. This reaction will need reagent PhPdI(PPh₃)₂ and solvent hexamethylphosphoric acid triamide. The reaction time is 0.5 hour at reaction temperature of 70 °C. The yield is about 87%.
