The majority of commodity chemicals, pharmaceuticals, and consumer materials are prepared in multistep syntheses and many require catalysts to achieve high yield and selectivity toward the desired products. A drawback of multistep syntheses is that they require time, energy, and exhaustive processes in between reaction steps to separate and purify reaction intermediates. Alternative methods that enable multistep sequences would obviate the need for costly intermediates. A particularly attractive approach is integrated catalysis, in which multiple catalysts are carefully controlled and positioned to allow efficient multistep reaction sequences to operate synchronously, funneling intermediates from one catalyst to the next. The classification of different catalytic processes is shown in FIG. . If only one linear reaction sequence occurs, then it is considered a cascade or domino process. If multiple reactions are proceeding simultaneously, then it is considered a tandem process. Integrated catalysis is a special case of tandem catalysis, in which multiple catalysts operate orthogonally at the same time or are switched on/off using external triggers. The recent literature has many excellent examples of cascade or tandem processes, but integrated processes are rarely reported.
