Abstract:

Q2MM is a method designed to allow application of molecular mechanics calculations to transition states in chemical reactions. It is one of the few methods available that allow determination of a complete set of low-energy transition states for medium-sized systems, and thereby gives a unique opportunity to investigate kinetic selectivity, in particular stereoselectivity. The current review will give an outline of the procedure, an overview of the types of reactions that have been studied using this method, and summarize the factors affecting the accuracy of the results.
