Activated Carbon Supported Hafnium(IV) Chloride as an Efficient, Recyclable, and Facile Removable Catalyst for Expeditious Parallel Synthesis of Benzimidazoles
A highly efficient method for parallel synthesis of a diversity of 1,2-disubstituted benzimidazoles from <i>N</i>-substituted phenylenediamines and aldehydes has been developed by using 10 mol% HfCl<sub>4</sub> on activated carbon (HfCl<sub>4</sub>/C) as the catal...
