Nano n-propyisulfonated γ-Fe2O3 (NPS-γ-Fe2O3) as a magnetically recyclable heterogeneous catalyst for the efficient synthesis of 2-indolyl-1-nitroalkanes and bis(indolyl)methanes

摘要

Nano n-propylsulfonated γ-Fe2O3 (NPS-γ-Fe2O3) was used as a new magnetically recyclable heterogeneous catalyst for the efficient synthesis of indole derivatives, such as 2-indolyl-1-nitroalkanes and bis(indolyl)methanes.
