Hydrogenation of alkenes and alkynes takes place in presence of certain catalysts. In Sabatier Senderen’s reaction, the addition of hydrogen takes place in presence of Raney nickel catalyst. Platinum and palladium can also be used catalyst in these reactions. These are heterogeneous catalyst and used in finely divided state. Experimentally, it is observed that less crowded alkenes absorb H2 with faster rate. Controlled hydrogenation of alkyne in presence of Lindlar’s catalyst yields cis product i.e., ‘cis’ alkene. Thus, in presence of Lindlar’s catalyst ‘syn’ addition takes place. The relative rate of hydrogenation follows the order
Non-terminal alkynes are reduced in presence of Na or Li metal dissolved in liquid ammonia. In this reaction, anti-addition of hydrogen results into the trans-product.
The product of the following reaction is :
