Abstract

Complete control of the product of a catalytic reaction can be achieved on the basis of catalyst structure, even when the reaction conditions are nearly identical. Catalyst-controlled selectivity is well established for enantioselective catalysis but less formulated for catalytic regio-, chemo-, or product-selective reactions. This Review describes selective transformations of the same starting materials into two or more different products simply by the choice of catalyst. By collecting and highlighting examples of selective catalysis, we hope that the field will be encouraged by the progress that has been made while bringing attention to unmet needs in the design and mechanistic understanding of selective catalysts.
