Bis(trimethylsilyl)acetylene
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)?). TiCl4-Et2AlCl catalyzed Diels-Alder reaction of BTMSA with norbornadiene has been reported.
