说明

一般描述

(4-Bromophenylethynyl)trimethylsilane can be synthesized by the palladium catalyzed reaction between 4-bromo-1-iodobenzene and trimethylsilylacetylene.[1] It undergoes Buchwald-Hartwig coupling with para-substituted diphenylamines.[2]

应用

(4-Bromophenylethynyl)trimethylsilane may be used to synthesize:

• 1-bromo-4-ethynylbenzene[1]
• 4-(4-bromophenyl)-3-butyn-2-one[3]
• 4-ethynyl-4′-tert-butylbiphenyl[4]
• 1,4-bis[2-(4-bromophenyl)ethynyl]-2,5-dihexylbenzene[5]
