[39] All optimized structures were confirmed to have no negative frequency by frequency calculations. All transition structures were found to have only one negative eigenvalue with the corresponding eigenvector involving the formation of newly created C-C bonds. The transition states reported were shown to belong to the studied reaction through the intrinsic reaction coordinate (IRC).
