Hey everyone,
dose somebody also had issues removing the Raney-Nickel after a hydrogenation with dihydrogen? I was reducing a nitrile-function which I can only do by using Raney-Ni.
For workup I used a huge pad of celite and after the column chromatography with DCM/MeOH over silica, still seems that the fractions have some sort of metal complexes ort particle’s.
Would be grateful for some help!
Thanks,
Péter
