Ketones undergo smooth rearrangement with TMSN 3 in the presence of FeCl 3 under extremely mild conditions to provide the corresponding amides, imides and lactams in good yields with high selectivity. This method is very useful for the preparation of a wide range of amides, imides and lactams from ketones. The use of FeCl 3 makes this method simple, convenient and cost-effective.
Various benzylic, allylic and tertiary alcohols are converted into their corresponding amides in excellent yields, when reacted with various nitriles in the presence of 0.5mol% of phosphomolybdic acid supported on silica gel at 80°C under solvent-free conditions. The use of PMA–SiO 2 makes it quite simple, more convenient and environmentally benign. This method offers several advantages such...
