One of the greatest challenges in modern chemistry is to perform efficient transformations of organic molecules under environmentally friendly conditions with the aid of catalyst. In the past few decades, high performance catalysts have been designed for a variety of organic transformations. By using an appropriate catalyst, a number of reactions that would not usually proceed have been accomplished and ingenious reaction selectivities have been attained. These developments stimulated remarkable progress in the field of catalytic organic chemistry. Under these situations, we focused our attention on transition metal-catalyzed dehydrogenative transformations of organic molecules based on the cooperative catalysis by iridium and a functional ligand. In this paper, our recent investigations on (1) dehydrogenative oxidation of alcohols into carbonyl compounds, (2) hydrogen storage systems based on the reversible interconversion between saturated N-heterocyclic compounds and unsaturated aromatic N-heterocyclic compounds by catalytic dehydrogenation and hydrogenation, and (3) efficient hydrogen production from methanol-water solution under very mild conditions, will be reported.
