    Description

    Applications
    BTMSA is used as starting reagent in the synthesis of functionalized 4-R-1,2-bis(trimethylsilyl)benzenes. It is also used in the synthesis of (+)-brasilenyne2 and (β-diketanato)Ag(BTMSA). Bis(trimethylsilyl)acetylene is a ligand that binds to a central metal ion (e.g. Titanium) to create a coordination complex. One of its complexes, Permethyltitanocene-bis(trimethylsilyl)acetylene, is a catalyst for the head-to-tail dimerization of 1-alkynes (e.g. 3-Penten-1-yne [P227430]).

    Solubility
    Not miscible or difficult to mix in water. Soluble in Chloroform and Methanol.

    Notes
    Store away from oxidizing agents. Do not store together with acids.
