Bis(trimethylsilyl)acetylene, 99%

Application

Bis(trimethylsilyl)acetylene (BTMSA) was used as starting reagent in the synthesis of functionalized 4-R-1,2-bis(trimethylsilyl)benzenes. It was also used in the synthesis of (+)-brasilenyne and (β-diketanato)Ag(BTMSA).

General description

Bis(trimethylsilyl)acetylene (BTMSA) participates as nucleophile in Friedel-Crafts type acylations and alkylations. BTMSA undergoes rhodium catalyzed addition reaction with diarylacetylenes. It undergoes cycloaddition with 1,5-hexadiynes in the presence of CpCo(CO)₂ (Cp=cyclopentadienyl) to form benzocyclobutenes. Structure of BTMSA was characterized by a centre of inversion present on triple bond (length=1.208(3)Å). TiCl₄-Et₂AlCl catalyzed Diels-Alder reaction of BTMSA with norbornadiene has been reported.
