A N2-bridged diiron complex [Cp*­(Ph2PC6­H4S)­Fe]2­(μ-N2) (1) has been found to catalyze the hydroboration of N-heteroarenes with pinacolborane, giving N-borylated 1,2-reduced products with high regioselectivity. The catalysis is initiated by coordination of N-heteroarenes to the iron center, while the B–H bond cleavage is the rate-determining step.
