Polymer‐Stabilized Palladium Nanoparticles for the Chemoselective Transfer Hydrogenation of α,β‐Unsaturated Carbonyls: Single‐Step Bottom‐Up Approach

Polypyrrole stabilised palladium nanoparticles show good catalytic efficiency for the chemoselective transfer hydrogenation of α,β‐unsaturated carbonyl compounds. The catalyst is very specific and selectively hydrogenates the olefins or acetylenes only, without affecting the carbonyl moiety, with an excellent yield of products for a wide range of substrates.
