you will need it.
There will be yields if there is enough time for the reaction. Two days up to several weeks. But you will have to use an very big amount of catalyst.
If nickel is used in a microwave/CTH reaction for the reductive Alkylation there might be a chance. Yields? Dunno.
Elevated pressure doesn't appear to be necessary for what I intend to use it for, at least according to the amphetamine from P2NP on Rhodium's site (if it's wrong, I'd hope he'd edit it). Amphetamine is not my goal, but it's the same basic reaction as far as I understand - and if I'm wrong, I'll find out one way or another.
Perhaps you should ask Rhodium himself how far he is willing to take over responsibility for the correctness of the content of his webpage.
Yes and as it´s obvious that ya don´t want to know, ya just want to believe I will leave you on this.
have fun stay safe

Is it this you are talking about?

If thus is so, a short comment:
Ni catalysts are known to need elevated temperature, elevated pressure (>80bar) and basic conditions for being used in reductive amination/alkylations.
This information can be found in basic and sophisticated literature, on the web, from catalyst manufacturers and patents.
In the "writeup" is no pressure applied, no heat and the catalyst is washed to neutral and to the reaction is acid added.
I would be the first to praise the lord loud if it comes out to be as easy.
But I am sure that it is only another BS "writeup" which floates around here at the HIVE. There are and always have been some psychopathics who feeded their ego by posting "fiction science".

The Urushibara Nickel reduction is not an ordinary hydrogenation, if that is what you were hoping to see. It is a catalytic transfer hydrogenation (CTH), where finely divided nickel is first made by dissolving aluminum metal in a solution of nickel(II)chloride:
NiCl2(aq) + Al(s) -> Ni(s) + AlCl3(aq)
Then this metal powder is used as a catalyst, where an acidified alcoholic solution of the nitroalkene is treated with more aluminum metal. As the aluminum dissolves, hydrogen is produced, which is adsorbed onto the Urushibara Nickel surface, and is then transferred to the substrate which is reduced.
2 Al + 6 H+ -> 2 Al3+ + 3 H2
Ni + H2 -> "NiH2"
"NiH2" + Nitrostyrene -> Ni + Phenethylamine

This is the hive bible on Urushibara catalysts.
On Rhodiums page there is also a great setup for an overhead stirrer that may be significant.

Good luck Spectral! Don't forget to report back on success or failure.
