Synthesis of indoles via dehydrogenative N-heterocyclization by supported platinum catalysts†
Abstract
We found the first heterogeneous Pt catalysts (Pt/Nb2O5 and Pt/HBEA) for the synthesis of indoles via acceptorless dehydrogenative cyclization of 2-(2-aminophenyl)ethanol, showing higher turnover number (TON) than previously reported catalysts.
