What is Lindlar's catalyst? Write its uses.
(N/A) Lindlar's catalyst is a form of partially deactivated palladium catalyst. It consists of palladium deposited on calcium carbonate $(CaCO_3)$ or barium sulfate $(BaSO_4)$,which is then poisoned with lead acetate or quinoline.
Its primary use is the partial hydrogenation of alkynes to form $cis$-alkenes. This reaction is stereoselective,ensuring the addition of hydrogen occurs on the same side of the triple bond.
