Abstract

The insertion of titanocene, prepared from the corresponding dicarbonyl complex, into SS bonds of S7NH and S7NMe affords the complexes 1 and 2, respectively, which are suitable as precursors for large SN rings. The treatment of 2 with SCl2 and S2Cl2 yields the imides S8NMe and S9NMe, respectively.
