Theoretically predicted thermodynamics and C=O IR stretching frequency (cm−1) of (a) 1:1 and 2:1 complex formed from Fc and Ac and (b) thermodynamics of chloride migration. Reaction energies (kcal/mol) were obtained at ωb97X-D3/def2-TZVP/SMD(DCE) level of theory. Color code: Fe, cyan; Cl, magenta; O, red; C, gray; H, white.
