Catalytic Hydrogenation of Alkenes and Alkynes

When we discussed basic information regarding homogeneous and heterogeneous catalysis, we mentioned hydrogenation of alkenes in both of these contexts. Now let's get more specific and describe the mechanism of this precise catalysis in both paradigms. Heterogeneous hydrogenation is used for industrial applications. For fine chemicals and pharmaceuticals, and homogeneous approach is used, and the catalytic cycles, whether hydrogen first or olefin first, are a little bit involved. Let's go through them together!
