Thionethiol
Thionethiol is a hypothetical organosulfur compound with the chemical formula CH3CSH. It is the thioenol tautomer of thioacetaldehyde (CH3CHS). In thioaldehydes and thioketones, the thione form (C=S) is generally more stable than the thiol form (C-SH). Therefore, thioacetaldehyde is expected to exist primarily in the thione form, with thionethiol being a less favored isomer.
The structure of thionethiol would involve a methyl group (CH3) attached to a carbon atom, which is
Due to the inherent instability of the thiol tautomer in such systems, thionethiol is not a commonly
