    CAS No.: 1450-14-2 Formula: C6H18Si2 Molecular Weight: 146.37800

    Description

    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
