Abstract

Dihydrogen reactions are mainly reaction‐center‐mediated. In a systematic approach, these reactions are divided into the steps of splitting of H~2~ and H‐atom transfers with homolytic and heterolytic splitting at mono‐ and dinuclear reaction centers, and further homopolar H transfers in Wilkinson‐type hydrogenations (insertion and reductive elimination) and heteropolar transfers in ionic hydrogenations (hydride before proton, proton before hydride, simultaneous hydride/proton transfers). Based on these categories, transfer hydrogenations are also surveyed. A separate class of reactions is one‐electron reactions of dihydrogen.
