一般說明

(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.

應用

(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
