Lindlar catalyst: Alkynes can be selectively reduced to an alkene by reaction with hydrogen in presence of Pd/BaSO4, Lindlar catalyst. The Lindlar catalyst is a heterogeneous catalyst that consists of palladium deposited on barium sulfate which is then poisoned with various forms of lead or sulfur. It is used for the hydrogenation of alkynes to alkenes. Lindlar catalyst converts alkyne to a cis alkene.In the first step of the reaction, the alkyne is reduced into the cis alkene.In the second step of the reaction ozonolysis of alkene takes place. In the ozonolysis reaction, the carbon-carbon bond of alkene has been replaced by a carbonyl group. Alkenes can be oxidized with ozone to form a carbonyl compound. The ozonide formed in this can be reduced into a carbonyl compound when it reacts with dimethyl sulfide.
