H2/Pd vs H2/Raney Nickel
« on: July 11, 2019, 04:58:27 AM »
Is there a difference between the two in a matter of reduction of functional groups? According to masterorganicchemistry website reactions H2/Pd can reduce Nitriles/Nitro/imines as well as aldehyde/ketones with enough pressures but i have seen videos in which they say it is preferred to use H2/Raney Ni to reduce carbonyls and nitriles, or H2/pd is good enough for all of them groups lets say?

Thanks in advance

Apart few exceptions, both hydrogenation catalysts are about, equally effective.
However, Pd/C catalyst figures in the literature more often because its use in the lab, is more convenient.
On the other hand, Ni(R) is preferred for industrial application due to the quite lower price.
