[ReH(SH)2(PMe3)4]: A catalyst for fundamental transformations involving H2 and H2S
Not a poison! In contrast to the high reactivity of 1, the corresponding trihydride [ReH3(PMe3)4] 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).

Buta-1,3-diene Hydrogenation on a Deuterium Sulphide-treated Molybdenum Disulphide Catalyst
Deuterium, introduced as D2S to a molybdenum disulphide catalyst, has been found to exchange with gas-phase hydrogen and to be incorporated into hydrocarbon products when buta-1,3-diene is hydrogenated on the catalyst; evidence is presented for the participation of hydrogen present on the surface as SH groups.
