Abstract [en]

The combined use of Lewis acids (electron-pair acceptors) and Lewis bases (electron-pair donors) for simultaneous activation of electrophiles and nucleophiles has proven to be a synthetically highly versatile concept. Catalytic systems consisting of Lewis acid and Lewis base functions, present in a single molecule or in separate molecules, frequently lead not only to enhanced reactivity, but also to increased chemo- regio- and stereoselectivity as a result of organized transition states. Synthetically versatile examples of such dual activation are found in reactions incorporating additions to carbonyl functions, ring opening reactions, cycloaddition reactions, and polymerizations.
