This invention relates to a method for the novel preparation of 1-adamantanecarboxamides and 1-adamantaneacetamides. Adamantanecarboxamides and adamantaneacetamides are prepared in high yields (80-100%) by treating adamantanecarboxylic acid and adamantaneacetic acid with N,N-diethyl-1,1,2,3,3,3-hexafluoropropylamine, followed by addition of aqueous ammonia or the appropriate amine. The procedure, carried out at ambient temperature using common laboratory equipment, is both convenient and rapid, requiring no more than one or two hours. Several reactions can be carried out simultaneously.

We describe an iron-catalyzed amidebondformation from readily available carboxylic acids and isocyanates. This method utilizes an abundant and biocompatible iron catalyst and easily accessible starting materials, generates CO2 as the only byproduct, and features broad substrate scopes with good functional group compatibility. Therefore, it provides a cost-effective and practical protocol to access
