Description
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]).
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
