TiO2 nanoparticles: an efficient heterogeneous catalyst for synthesis of bis(indolyl)methanes under solvent-free conditions
摘要:
Some bis(indolyl)methanes have been synthesized, in excellent yields, under solvent free conditions, by reaction of indoles with aromatic and aliphatic aldehydes in the presence of nano titanium(IV) oxide as an efficient, heterogeneous, reusable, and non-toxic catalyst.
