(22) Semiempirical computational procedure: All the calculations were done at the RHF level. The first input files for MOPAC 6.00 were created by means of SYBYL 6,01 (Tripos Associates, Inc.: 16995 Hanley Rd, Suite 303, St. Louis, MO 63144-2913) for IBM RS/6000 computers. The norm of the gradient of these draft structures were then fully optimized using TS subroutines. Finally, all the transition structures were characterized by only one negative force constant.

(25) Ab initio computational procedure: All the calculations were done at the RHF 3-21G level. The first input files for GAMESS were the corresponding fully characterized AM1 transition structures. The saddle point searches were carried out in cartesian coordinates. The computed AM1 hessian matrices were fed into GAMESS. Finally, when the saddle points were located, the hessian matrices were not recomputed at the 3-21G level of theory due to system limitations. Thus zero point energies corrections could not be applied.
