Without the addition of catalysts and solvents,15 known bis(indolyl) alkane compounds were synthesized under mild conditions from substituted indoles and substituted benzaldehydes in 65%~91% yields.The mechanism of this condensation reaction was discussed and the relationship between reaction speed and substituent groups was described.All the compounds synthesized were confirmed by 1H NMR,13C NMR and IR analysis.
