Selective reduction catalyst
Palladium-activated carbon diphenyl sulfide complex   (Pd: 8.5 ~ 11.5%)

This is a contact catalyst for reduction in which diphenyl sulfide is immobilized as a catalyst poison to palladium-activated carbon complex. It is useful for selective reduction of olefin, acetylene, nitro groups and azides in the coexistence of aromatic ketones, aromatic halogens, benzyl esters and N-Cbz protecting group.
