Zirconyl Chloride: An Efficient, Water-Tolerant, and Reusable Catalyst for the Synthesis of N-Methylamides

Abstract ZrOCl 2 ˙8H 2 O is a highly effective, water-tolerant, and reusable catalyst for the direct condensation of carboxylic acids and N,N′-dimethylurea under microwave irradiation to give the corresponding N-methylamides in moderate to excellent yields. Notably, ZrOCl 2 ˙8H 2 O is a potentially...

Description
Summary:Abstract ZrOCl 2 ˙8H 2 O is a highly effective, water-tolerant, and reusable catalyst for the direct condensation of carboxylic acids and N,N′-dimethylurea under microwave irradiation to give the corresponding N-methylamides in moderate to excellent yields. Notably, ZrOCl 2 ˙8H 2 O is a potentially useful green catalyst due to its low toxicity, easy availability, low cost, ease of handling, easy recovery, good activity, and reusability.
