1. Group (IV) Metal-Catalyzed Direct Amidation : Synthesis and Mechanistic Considerations
Abstract : The amide unit constitutes the backbone of proteins, and it is present in a large number of pharmaceutically active molecules, polymeric materials such as nylon and Kevlar, as well as in food additives like aspartame. Amides are produced in enormous amounts every year, thus, environmentally friendly and selective methods for their formation are of great importance. READ MORE
