Computed energies of minima and transition structures on the potential energy surface for conversion of model benzynes I and VI into silyl ether trapped products V and VIII (panels A and B, respectively). Selected dihedral and internal bond angles are given for TSs II, IV, and VII. [M06-2X/6-31G(d); enthalpic energies (kcal·mol−1) are given in panels A and B. Energies for each species using three basis sets are given in panel C.
