Activation of SO2 by [Zn(Cp∗)2] and [(Cp∗)ZnI-ZnI(Cp∗)]

Abstract

Interesting reactivity was observed in reactions of SO2 with [Zn(Cp∗)2] and [(Cp∗)ZnI-ZnI(Cp∗)]. These reactions proceeded with insertion of SO2 into the Zn-C bonds. Spectacularly, the lability of the C-S bond in the O2SCp∗ ligands led to the thermal decomposition of [Zn(O2SCp∗)2(tmeda)] to afford [Zn2(μ-SO3)(μ-S2O4)(tmeda)2].
