Amines are one of the most important functional groups in organic chemistry and are ubiquitous in material science, dyes, agrochemicals, and pharmaceutical agents. To date, the most widespread synthetic approaches to generate amines are via N-alkylation, reductive amination of a carbonyl compound, and amide reductions. Although these approaches are routinely used, they do suffer from pooratom economy, deleterious onward reactivity, and access/cost of starting materials. Another well-established approach towards the synthesis of amines is hydroboration of compounds containing unsaturated C-N bonds, which has garnered renewed interest due to high selectivity and mild reaction conditions. The reduction of nitriles via hydroboration selectively furnishes diborylamine moieties which can readily undergo hydrolysis to generate free primary amines, unlike hydrosilylation which forms a mixture of the mono-silylated imine and disilylamine products. Hydroboration can also be successfully applied as a viable route to access saturated N-heterocycles from the corresponding N-heteroarenes, which are prevalent in bioactive molecules. To date, a wide range of complexes from across the periodic table are known to successfully catalyze the hydroboration of unsaturated C-N bonds, however many show only moderate catalytic activity and are deemed unattractive due to their precious or pyrophoric nature. As one of the most abundant metals on earth, iron offers a level of sustainable and longstanding availability, accompanied by low toxicity that is unorthodox compared to other transition metals. The use of iron complexes in the hydroboration of unsaturated C-N bonds has been overshadowed by work with precious metals, however, in recent years a range of structurally diverse catalytically active iron complexes have emerged (Figure ). The first example of ironcatalyzed nitrile hydroboration was reported by Nakazawa using a cooperative iron-indium heterobimetallic system, 1a. Findlater and co-workers reported an iron complex bearing the redox active bis(imino)acenaphthene (BIAN) ligand for nitrile hydroboration without the use of an exogenous activator, 1b. Recently, Hashimoto and co-workers reported the use of an iron silyl-NHC complex 1c with activation via UV irradiation (> 300 nm) to promote nitrile reduction with HBpin. There has been even less development in iron catalysis for the functionalization of N-heteroarenes, in 2017 Tung and Wang reported a N2-bridged diiron complex, 1d, and showed it to catalyze the selective 1,2-hydroboration of N-heteroarenes. Liang and Song also utilized a piano stool iron(II) complex, 1e, for the 1,4-
