Frustrated Lewis Pair Chemistry: Searching for New Reactions

Gerhard Erker, Universität Münster


The attachment of very bulky substituents at the core atoms of Lewis acids and bases can effectively hinder their neutralizating Lewis pair formation. The resulting “frustrated Lewis pairs (FLPs)” then offer the possibility to undergo cooperative reactions with added substrates. The cooperative action of intra- as well as intermolecular FLPs has indeed led to the disclosure of a variety of new reactivities. Metal-free activation of dihydrogen is a prominent example. This and several other examples of FLP behavior will be presented and discussed in this lecture. This may involve some new reactions of carbon monoxide and nitric oxide and the formal similarity of some metal-free FLP reactions to metal coordination chemistry. Some new polyfunctional FLP examples will be presented, which have led to some rather unusual and unprecedented chemical behavior. The lecture shall also focus to some extent on reactions of frustrated Lewis pairs and strongly electrophilic boranes involving radicals, and a very simple borane catalyzed reaction maybe presented.
