Catalytic dehydrogenation of feedstock chemicals, such as alcohols and amines to value-added products with the concomitant generation of dihydrogen is of much interest in the context of hydrogen economy and is an effective alternative to the classical oxidation reactions. Despite a number of homogeneous catalysts being identified for the acceptorless dehydrogenation, the use of high price and limited availability of precious metals and poor recovery of the catalyst have spurred interest in catalysis with more earth-abundant alternatives, especially iron. However, no report has described a reusable iron-based heterogeneous catalyst for oxidant-free and acceptorless dehydrogenation reactions. Here we replace expensive noble metal catalysts with an inexpensive, benign, and sustainable nanoscale iron catalyst for the efficient acceptorless dehydrogenation of N-heterocycles and alcohols with liberation of hydrogen gas.1 aJaiswal, Garima1 aLandge, Vinod, G.1 aJagadeesan, Dinesh1 aBalaraman, Ekambaram  uhttps://library.ncl.res.in/content/iron-based-nanocatalyst-acceptorless-dehydrogenation-reactions02097nas a2200169   4500008004100000245010400041210006900145260000800214300001400222490000600236520146300242100002501705700003001730700002001760700002101780856012601801       2017                        eng d00aIron-catalyzed dehydrogenation reactions and their applications in sustainable energy and catalysis0 aIroncatalyzed dehydrogenation reactions and their applications i  cAUG  a3177-31950 v73 aInspired by nature, chemists have designed new catalysts in the pursuit of selective bond activation and chemical transformations. Emergent biological systems often use earth-abundant first-row transition elements as catalytically active sites to facilitate specific and highly selective chemical processes. The design of a new catalytic system based on abundant and inexpensive catalysts, particularly the iron-based catalysts, for fundamentally significant synthetic transformations under environmentally benign conditions is an important paradigm in chemical synthesis. In recent times, iron-based catalytic systems have shown unprecedented reactivity in the acceptorless dehydrogenation reactions of feedstock chemicals, with the liberation of molecular hydrogen as the by-product, and have enabled greener chemical synthetic methods and alternative energy storage systems. Indeed, it has been demonstrated that the proper design of iron catalysts by judiciously choosing ligands, can aid in the development of new sustainable energy storage systems and catalysis. This tutorial review focuses on the recent development of iron-based dehydrogenation reactions of fundamentally important feedstock, as a route to sustainable chemical synthesis and energy storage applications. The emerging area of the iron-based dehydrogenation strategy provides an opportunity to make industrially applicable, cost-effective and environmentally benign catalytic systems.1 aBalaraman, Ekambaram1 aNandakumar, Avanashiappan1 aJaiswal, Garima1 aSahoo, Manoj, K.  uhttps://library.ncl.res.in/content/iron-catalyzed-dehydrogenation-reactions-and-their-applications-sustainable-energy-and
