• Bis­(trimethylsilyl)­sulfurdiimide S­(NSiMe3)2 reacts with equimolar amounts of Me2Zn and Cp*2Zn either with insertion into the metal–carbon bond and formation of the expected S-methyl diimidosulfinate complex [MeZnN­(SiMe3)­S­(Me)­NSiMe3]2 1 or the unexpected complex {Me3SiNS­[N­(SiMe3)­SNSiMe3]­N­(SiMe3)­Zn}2 2. Insertion reactions were also observed with Cp*MMe3 (M = Ti, Zr, Hf), yielding Cp*­(Me)2M­[Me3SiNS­(Me)­NSiMe3] (M = Ti 3, Zr 4, Hf 5), whereas the corresponding Cl-substituted derivatives Cp*­(Cl)2M­[(Me3SiNS­(Me)­NSiMe3] (M = Ti 6, Zr 7, Hf 8) were obtained from salt elimination reactions of Li S-methyl diimidosulfinate (Me3SiN)2S­(Me)­Li­(thf)]2 9 with Cp*MCl3. Compounds 1–8 were characterized by heteronuclear NMR (1H and 13C) and IR spectroscopy, and the solid state structures of 1–5 and 9 were determined by single crystal X-ray diffraction.
