Synthesis of unsymmetrical aryl-ethynylated benzenes via regiocontrolled Sonogashira reaction of 1,3,5-tribromobenzene. Kamal M. Hassaneen; Hyam A. Abdelhadi; Mohamed S. Ahmed; Mohamed A. Sonogashira coupling of trimethylsilylacetylene with 4-alkyloxyiodobenzenes gave 2- 4- alkyloxy phenyl ethynyltrimethylsilanes which undergo deprotection via removal of TMS-group using tetrabutylammonium fluoride TBAF in THF at room temperature to afford the corresponding terminal 2- 4- alkyloxy phenyl acetylenes. Regiocontrolled Sonogashira cross-coupling of 1,3,5-tribromobenzene with the terminal arylacetylenes in aqueous medium resulted in the formation of mono-, di- and tri-alkynylated benzene derivatives in moderate to good yields.
