A computational evaluation of the structure and heat of formation of halotrifluoromethyl-sulfane compounds XC(O)SCF₃ (X = F and Cl)

Enthalpies of formation (ΔH⁰ <sub>f298K</sub> (g)) are calculated for syn and anti conformers of FC(O)SCF₃ and ClC(O)SCF₃ using the atomization methods with the Gaussian-n composite methods for which experimental values do not exist. DFT approaches and MP2 methods are employed to optimiz...

Sumario:Enthalpies of formation (ΔH⁰ <sub>f298K</sub> (g)) are calculated for syn and anti conformers of FC(O)SCF₃ and ClC(O)SCF₃ using the atomization methods with the Gaussian-n composite methods for which experimental values do not exist. DFT approaches and MP2 methods are employed to optimize the molecular geometries of XC(O)SCF₃ (X = F and Cl). Excellent results are obtained with the reported experimental data.
