产品介绍：在 CpCo(CO)2（产品目录号245259）存在的条件下，可与 1,5-己二炔发生环加成反应生成苯并环丁烯。硅基保护基，有机合成。applicationBis(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).product descriptionBis(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.
