Treatment of
Pt(PPh3)3SO2 with
RS-phthalimide, a source of RS+, gives complexes
containing ligands of the type RSS(O)2
-,
the first of their kind. The reaction models the industrially
important Claus process (2H2S + SO2 →
3/8S8 + 2H2O) by
simulating the attack of H2S on surface coordinated
SO2. Sulfur−sulfur bond formation, as observed in
this work, is a necessary characteristic of the heterogeneously
catalyzed Claus process.
