Abstract
Acyloin (R1COCH(OH)R2) and its derivatives react via intramolecular double proton transfer. Previous MO calculations have shown that this proton transfer had two types of transition states (TSs), one with proton transfer occurring ahead of hydride transfer and the other with the reverse situation. When R1 = R2, the two TSs are identical, and thus the reaction should go through the two TSs equally. However, it is unclear whether the same is true with dynamics effect. But, if this theory works with dynamics effect is unclear. The results of theoretical analyses will be reported.
