(4-BROMOPHENYLETHYNYL)TRIMETHYLSILANE Usage And Synthesis

Uses

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

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

General Description

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