Multi-catalysis is an emerging field targeting the development of efficient catalytic transformations to quickly convert relatively simple starting materials into more complex valueadded products. Within multi-catalytic processes either multiple catalysts execute single reactions or precise sequences of multiple catalytic reactions occur in a 'one-pot' fashion. Attractively, multi-catalytic protocols not only enable transformations that are inaccessible through classic approaches, but also are able to significantly reduce the time, waste, and cost of the synthetic processes, making organic synthesis more resources efficient. In this Perspective article, we review different strategies in multi-catalysis that bring distinct challenges and opportunities. We divide this overarching field into three main categories: cooperative, domino, and relay catalysis. Each category is described along with representative examples to highlight its features. Special emphasis is dedicated to relay catalysis, which is further discussed in its sub-categories. Lastly, we provide an analysis of systems that incorporate higher levels of complexity and further underscore the potential of multi-catalytic systems.

The catalytic performance of the novel framework {[Cu3Lu2(ODA)6(H2O)6]·10H2O}n was tested in the oxidation of alkenes and benzylic hydrocarbons, using tert-butyl hydroperoxide (TBHP) and molecular oxygen (O2) as oxidants.
