The MP2/6-311G(d) level of theory has been applied to answer the question of how the geometry and total energy changes with respect to lengthening of the S-Cl bond in Cl-SH(OH)-Cl. The results predict that the title compound would readily dissociate forming HC1 and Cl-S(H)O. The dissociation energy is calculated at the G2(MP2) and CCSD (T) /6-311G(d) levels of theory with zero-point and basis set corrections. Our finding that the sulfurane structure is trapped at a high energy minimum relative to the HCl and SH(O)Cl component molecules implies that sulfurane synthesis from those components is energetically an uphill process.
