Recent Advances in Iron- and Cobalt-Complex-Catalyzed Tandem/Consecutive Processes Involving Hydrogenation

Abstract

Complexes with non-noble metals are becoming more and more important in organometallic and organic chemistry. This mini-review covers the recent progress in cobalt- and iron-catalyzed consecutive reactions involving at least one hydrogenation step. 1 Introduction 2 Synthesis of the Iron and Cobalt Complexes 2.1 Synthesis of the Iron Complexes 2.2 Synthesis of the Cobalt Complexes 3 Hydrogenation of Carboxylic and Carbonic Compounds 3.1 Hydrogenation of Esters and Amides 3.2 Hydrogenation of Nitriles 3.3 Hydrogenation of Carbon Dioxide and Carbonates 3.3.1 Hydrogenation of Carbon Dioxide 3.3.2 Hydrogenation of Carbonate and Bicarbonate 4 Processes Involving a Hydrogenation Step 4.1 Reductive Amination 4.2 Alkylation of Amines 4.3 Alkylation of Ketones 4.4 Alkylation of Allylic Alcohols 5 Conclusion
