The decomposition pathways of chloromethanol have been studied by ab ii cal
culation. Equilibriums and transition states have been optimized at the UMP
2(full)/6-31G(d) level. The single point energies have been obtained at hig
her level of G3(MP2). Four transition states and eight reaction pathways ha
ve been revealed and the most favorable reaction to decomposition pathway i
s the 1, 2-HCl elimination, which is consistent with the former scientist's
conclusion.
