7.1 Introduction
During recent decades, impressive efforts have been made by the organic
chemistry community to synthesize ever more complex molecular structures.
Unfortunately, these synthetic routes are often time consuming and expen-
sive and produce large amounts of wastes. Consequently, producing high-
value-added fine chemicals, such as pharmaceutical, agrochemical, dye or
monomeric compounds is still economically and environmentally chal-
lenging. Organic synthesis could be more effective if multiple catalysts act
simultaneously or alternately in a single reactor with multiple reagents or
reactants. These 'multicatalytic' reactions would maximize yield and min-
imize time, effort and waste associated to the synthesis of high-value-added
molecules.
