Rehybridization as a general mechanism for maximizing chemical and supramolecular bonding and a driving force for chemical reactions.
Dynamic variations in hybridization patterns (rehybridization) were analyzed at B3LYP/6-31G** and MP2/6-31+G* levels. Computations clearly illustrate the generality of rehybridization in a variety of chemical phenomena, which involve structural reorganization in hydrogen-bonded complexes, nonhyperconjugative stereoelectronic effects in saturated heterocycles, Mills-Nixon effect, and contrasting substituent effects in cycloaromatization reactions.
