In a pair of compounds consisting of Lewis acids and Lewis bases this pair is prevented from neutralizing itself if both the subunits exhibit sufficient sterically hindrance. In those cases they exhibit the chemical properties of both components as reactive partners. Such "frustrated" Lewis Pairs (FLPs) react under 1,2-addition at organic π-systems. This type of activation mediated by frustrated Lewis pairs is a prototypical example of a cooperative interaction within a three-species-system. Within project A1 new "frustrated" Lewis pairs shall be developed derived from phosphorous/boron, nitrogen/boron and carbon/boron. We then want to investigate these systems in addition reactions with olefins, alkynes, ketones, aldehydes and similar substrates and analyze the mode of action of these transformations. Furthermore, we'd like to utilize these reactions for the modification of catalysts and polymerization reactions.
