A two-coordinate Fe(II) m-terphenyl complex acts
as a precatalyst for the hydroamination of isocyanates, affording
urea and biuret derivatives, with product selectivity accomplished
via modification of the reaction conditions. Using a more nucleophilic
amine facilitates the insertion of up to four isocyanates into the
N–H bond, affording triuret and tetrauret derivatives.
