The insertion of titanocene , prepared from the corresponding dicarbonyl complex, into SS bonds of S 7 NH and S 7 NMe affords the complexes 1 and 2 , respectively, which are suitable as precursors for large SN rings. The treatment of 2 with SCl 2 and S 2 Cl 2 yields the imides S 8 NMe and S 9 NMe, respectively.
