Capture of an <i>In Situ</i> Formed Distanna-S-heterocyclic Carbene
The planar, non-twisted distannene Sn<sub>2</sub>(TIPS)<sub>4</sub> (<b>1</b>, TIPS = Si<sup><i>i</i></sup>Pr<sub>3</sub>) reacts with CS<sub>2</sub> to form a tetrathiaethylene derivative via the dimerization of two S-heterocyclic carbenes (SHCs). These intermediary-formed SHCs can be transferred to palladium as ligands or captured with B(C<sub>6</sub>F<sub>5</sub>)<sub>3</sub> (BCF) and, furthermore, facilitate a new pathway for formation of the stannaethene SHC═Sn(TIPS)<sub>2</sub> by the reaction of <b>1</b> with (PPh<sub>3</sub>)<sub>2</sub>Pd-CS<sub>2</sub>. In addition to the characterization of the new complexes, theoretical calculations of the frontier orbitals were performed, which indicate a high π-acceptor character of the SHC.
