The first part mainly focuses on exhibiting high efficiency and selective pincer complexes employed as catalysts for dehydrogenation to obtain hydrogen from potential hydrogen storage materials, hydrazine borane. The first series of pincer catalysts used for dehydrogenation of hydrazine borane is Brookhart’s well-described catalysts as well as their 3,5-substituted analogs with electron withdrawing and electron donating groups. Then, iron(II) complexes bearing a PNP backbone were also utilized for dehydrogenation of the same substrate.
