Efficient syntheses of bis (1H-indol-3-yl)ethanones and bis (benzotriazolyl)ethanones via reaction of phenylglyoxals with indole or 1,H-benzotriazole in the presence B(HSO4)3 in solvent-free thermal and in aqueous media conditions are discribed. The syntheses have several advantages such as: generality, short reaction time, simple experiment and work-up procedures, excellent isolated yields
