I have 5% Pd/C and need a reaction to do...
Hello there fellow Chem enthusiasts. I've received a nice package in the mail and feel a little excited. There are plenty of options to do with such
an awesome, versatile catalyst. If you had the stuff, what would you do? Reduction seems to be the most obvious answer, but I recognized that this can
be more fun than that. Any ideas? Thank you advance. The day I do anything with this stuff I will of course include pictures. Cheers, friends.

Pretty much all Pd/C is used for is hydrogenations. If you don’t have the equipment or reagents though, keeping it as an investment is also fine -
it is a (or at least a mixture of a) precious metal.
Is the Pd/C impregnated at all (on zeolite or silica)? If so, it’d be a lot easier to recycle. If not, before any reaction, make sure you have a
procedure in place to recapture any and all of it from your rxn mix.
I personally wanted to look into reductive aziridine ring opening, as a new way to produce N-substituted isopropyl amines (internal alkenes can be
aminated electrochemically to aziridines then reduced).

I did these 2 experiments, the first one was hydrogenation (a product with flowers scent) and the second one dehydrogenation (into an aromatic
heterocycle)

How about a reduction with Al/H2O as the hydrogen source?
https://pubs.rsc.org/en/content/articlelanding/2017/gc/c6gc0...
Unfortunately I don't have access from home, so I can't quote a procedure right now.
The approach seems quite variable, you could reduce acetophenone to ethylbenzene or benzaldehyde to either benzylalcohol or toluene, depending on how
long you run it. Also double bonds and nitro groups are possible targets. Heck, even Ullman coupling of halobenzenes.
Fery gave some great examples how you can use Pd/C without a fancy pressure vessel or even a hydrogen tank, but aluminum and water would be even more
approachable for the home chemist.
The author affiliations don't make me think it's a bs paper, I'd love to give it a try myself if I could find the time.
