Abstract
Transition structures of LIH addition to cyclohexanone have been optim ized at the B3LYP/6-31G level. The bond lengths of the incipient bond become substantially elongated compared to the previous results at th e HF/3-21G level. It has been revealed that both torsional effects and hyperconjugative stabilization are of less importance for the pi-faci al diastereoselectivity.
