[ReH(SH) 2 (PMe 3 ) 4 ]: A Catalyst for Fundamental Transformations Involving H 2 and H 2 S

Thus, the usual view that sulfur poisons catalysts is clearly inappropriate in this case. The catalytic properties of 1 result from its difunctional nature with both protic (SH) an...

Summary:Not a poison! In contrast to the high reactivity of 1, the corresponding trihydride [ReH (PMe ) ] is kinetically inert. Thus, the usual view that sulfur poisons catalysts is clearly inappropriate in this case. The catalytic properties of 1 result from its difunctional nature with both protic (SH) and hydridic (ReH) sites; these sites communicate by an intramolecular exchange process (see scheme; X=OMe, SH).
