Using 5-bromoindole as raw material and PdCl2(dppf) as catalyst, N-alkyl-5-arylindole-3-carboxaldehydes were synthesized by the formylation, alkylation and Suzuki coupling reaction. The effects of catalysts, alkali reagents, solvents and the molar ratio of reactants on Suzuki coupling reaction have been surveyed. UV-Vis and fluorescence spectra of the title compounds in acetonitrile were also investigated.
