Monofunctional nanocatalysts

Of the two classes of reactions mentioned above, the use of a single catalyst to carry ont multiple reactions is a very promising approach. From a synthetic standpoint, it would be ideal since it is a relatively simple and economical approach [21], However, most cascade reactions of this type are essentially limited to reactions that have similar mechanisms (i.e., successive Pd-catalyzed cross-coupling), although some examples of sequence processes involving two or more different reactions have been described [22]. Here, we illustrate some monofunctional nanocatalyst examples and distinguish them from various catalytic active species. 

In this chapter we present the latest developments in cascade reactions catalyzed by heterogeneous nanocatalysts. Tandan transformations mediated by nanocatalysts can be divided into two types of reactions, involving monofunctional and multifunctional catalyzed processes (Scheme 8.1) [20], We highlight the synthesis approach of these novel nanocatalysts, which have been used successfully to produce active, selective, and dnrable heterogeneous catalysts, and summarize their properties and the cascade reactions which they promote. We then consider potential applications for these new catalysts and look into the future.
