Regarding the text available at the posted link, and the codeine -> dihydrocodeinone (hydrocodone) by rearrangement, can Nickel (Nickel metal or Nickel on Aluminum) be used in place of Pd/Pt in this reaction? I've read somewhere that it can but at some sacrifice to yields, however cannot recall the source.
Also if a powdered mixture of Nickel and Copper and roughly evening amounts was used, how would the presence of the Copper affect the reaction?
Thanks
