Lj. Hao et al., CLUSTERS AS MODELS FOR SURFACE CATALYSIS - A MODEL FOR SULFIDE EFFECTS ON PT-RE CATALYSTS, Journal of the Chemical Society, Chemical Communications, (18), 1994, pp. 2183-2184
By reaction with propene sulfide, one or two sulfur atoms are added to
the tetrahedral cluster cation [Pt-3{Re(Co)(3)}(mu-dppm)(3)](+)1(dppm
= Ph(2)PCH(2)PPh(2)), to give [Pt-3{Re(CO)(3)}S-n(mu-dppm)(3)](+) (n
= 1,2; n = 2, 3); the reactions provide an interesting model for sulfi
dation of heterogeneous Pt-Re catalysts.
