Multiple‐Metal (De‐)Hydrogenation‐Catalysed Processes

The use of different metals acting together in a synergistic way allows synthetic transformations that are not achievable by other means. Metal cooperation becomes important in catalytic processes for the synthesis of compounds with sophisticated structures or for difficult transformations. Rational design of multiple‐metal‐catalysed processes requires that the metal complexes and reaction conditions are compatible, which in general is not straightforward. A key feature for success found in all systems involving multimetallic processes is catalyst stability. The use of robust metal complexes increases the probability of success in the search for tandem catalytic processes. This microreview is based on the recent and most important findings of multiple‐metal‐catalysed processes that have involved (de‐)hydrogenation reactions. The field constitutes a research area that is full of potential, and it can be foreseen that relevant applications will be described in the near future.
