A new microwave assisted synthesis methodology has been presented for the preparation of the ferrocene amides. Ferrocene carboxylic acid was derivatised using direct 1H-Benzotriazole/SOCl2 methodolgy to prepare N-ferrocenoyl benzotriazole as a new starting material for the functionalization of ferrocene ring. N-ferrocenoyl benzotriazole was reacted with mono- and di-amines under microwave irradiation to prepare ferrocene mono- and di-amides in high purity and in good yield.
Electrophilic carboxamidation of ferrocenes with isocyanates

Ferrocenes undergo one-step carboxamidation by reaction with isocyanates in CF3SO3H solution. The chemistry is most efficient in excess superacid, and it has been accomplished with aryl and aliphatic isocyanates. In conversions with ferrocene carboxylic acids, isocyanates provide imides in good yields. A mechanism for this conversion is suggested involving carbamic acid anhydride formation and subsequent intramolecular reaction at the substituted cyclopentadienyl ring.
