Hexamethyldisilane is the organosilicon compound with the formula Si2(CH3)6, abbreviated Si2Me6. It is a colourless liquid, soluble in organic solvents.

The Si-Si bond in hexamethyldisilane is cleaved by strong nucleophiles and electrophiles. Alkyl lithium compounds react as follows:

Si2Me6 + RLi → RSiMe3 + LiSiMe3

Iodine gives trimethylsilyl iodide.

Me3Si−SiMe3 + I2 → 2 SiMe3I
