A Highly Efficient and Environmentally Friendly CMC-Supported Lanthanide Catalyst for One-pot Synthesis of Substituted I

A CMC-supported lanthanide catalyst was prepared from CMC and isopropoxy lanthanide. This solid Lewis acid catalyst was used in synthesis of substituted imidazoles under mild conditions, showing catalytic activity com-parable to the expensive lanthanide Lewis acid Ln(Otf)3. Furthermore, the catalyst could be readily recycled and reused for five times without any appreciable loss in catalytic activity.
