form

solid

Quality Level

reaction suitability

core: palladium, reaction type: Buchwald-Hartwig Cross Coupling Reaction, reaction type: Heck Reaction, reaction type: Hiyama Coupling, reaction type: Negishi Coupling, reaction type: Sonogashira Coupling, reaction type: Stille Coupling, reaction type: Suzuki-Miyaura Coupling, reagent type: catalyst

Application

Lindlar catalyst is a heterogeneous catalyst that is used mainly for the selective hydrogenation of alkynes to alkenes.
It can also effective catalyze:
  • selective hydrogenations of triple bonds to cis-double bonds
  • monohydrogenation of polyolefins
  • hydrogenation of azides to amines

Other Notes

~ 5% palladium on calcium carbonate; poisoned with lead.
