摘要：

The addition of protic acids to (eta(5)-cyclopentadienyl)(1-methylenethio)-HC, HS-ethylene-2-thiolato)cobalt(III) complexes (2) causes a Co-C bond cleavage in the three-membered cobaltathiirane ring to give (eta(5)-cyclopentadienyl)(halo or acido)(1-methylthio-HS-ethylene-2-thiolato)cobalt(III) complexes (3). In the crystalline state, these complexes have either syn- or anti-configuration with respect to halo (or acido) and the methyl or substituted methyl group attached to S. In some cases, complexes 3 exist in equilibria between syn- and anti-stereoisomeric forms in solutions. In solutions, an exchange of the coordinated anions occurs very easily.
