A fundamental tenet of the chemistry paradigm is that product selectivity is associated with energetic barriers to reactions. Dynamic effects are the exceptions. For some reactions, explicit consideration of the detailed motions and momenta of the atoms is required to explain product ratios or stereochemistry. However, such reactions have been rare, and dynamic effects would generally not be expected to be important in ordinary organic reactions. We have been investigating ways in which dynamic effects can play a critical role in many simple organic reactions in solution. Evidence for dynamic effects in a variety of reactions will be presented, and the impact of these dynamic effects on our general understanding of mechanisms and selectivity in chemistry will be discussed.
