RuCl3·3H2O was found to be an effective catalyst for one-pot reactions of benzylic alcoholes with indoles affording the corresponding
bis(indolyl)methanes under air atmosphere at room temperature in moderate to excellent yields. It is noteworthy that the
RuCl3·3H2O system displayed a preference for the primary versus secondary benzylic group of a benzylic diol in intramolecular competition
Keywords: Benzylic alcohol, Bis(indolyl)methane, RuCl3·3H2O, Indole.
