Treatment of aqueous formic acid (85%) with structurally diverse amines in the presence of a catalytic amount of sulfonic acid supported on hydroxyapatite-encapsulated-γ-Fe2O3 [HAp@-γ-Fe2O3] (0.9 mol.%) as a heterogeneous, reusable and highly efficient catalyst gave the corresponding formamides in good to excellent yields at room temperature. The magnetically catalytic system was recovered by-passing time consuming filtration operation by using an external magnet device. In addition to facility, this methodology, it also enhances product purity and promises economic as well as environmental benefits.

We developed a simple, practical, and catalytic method for the N-formylation of a wide variety of amines in the presence of molecular iodine as a catalyst under solvent-free conditions. This reaction is applicable to the chemoselective N-formylation of amino groups and -amino acid esters without epimerization.
