Abstract
Indium triflate catalysed the three-component one-pot reaction of indole 1 with a heteroimine generated in situ
under microwave irradiations and afforded predominately secondary indolyl amines 4 in excellent yields as well as bisindolyl
methane 5 in poor yields. The catalyst indium triflate can be recovered after the reaction and reused in the subsequent
experiments.
