    C 3 H 10 Si: Molar mass: gmol −1: Density: g cm −3: Melting point − °C (− °F; K) Boiling point: °C ( °F; K) Hazards. Trimethylsilyl cyanide is the chemical compound with the formula (CH 3) 3 SiCN. This volatile liquid consists of a cyanide group, that is CN, attached to a trimethylsilyl group. The molecule is used in organic synthesis as the equivalent of hydrogen is prepared by the reaction of lithium cyanide and trimethylsilyl chloride. LiCN + (CH 3) 3 SiCl → (CH 3) 3 SiCN + LiCl.

    Trimethylsilanol (TMS) is an organosilicon compound with the formula (CH 3) 3 SiOH. The Si centre bears three methyl groups and one hydroxyl group. It is a colourless volatile liquid.
