Abstract
Thioformaldehyde S,S-dioxide (sulfene) has a highly reactive C=S bond. The estimation of the length and strength of this bond depends largely on the quantum chemical approximation selected. In comparison with ab initio schemes, the use of semiempirical MINDO/3, MNDO, AM1, and PM3 schemes involves difficulties related to the parameters for sulfur.
