Hi, bees!
I have the same problem as discussed in this topic.
Swit would like to try the Pd-reduction rxn of ring-substituted phenyl-2-nitroethanes , but he can't pick out the right catalyst.
Please, prompt him in this holy affair
!
I have the next choice (from Sigma-Aldrich catalogue):
1) 10% Pd on activated aluminia (hydrogenation catalyst).
2) 10% Pd on activated charcoal (there is no notes, what is it... ) - so, it borns some doubts (as a matter of fact I've posted my question about it here) ...
3) 10% Pd on barium sulfate (hydrogenation catalyst).
4) 10% Pd on calcium carbonate (hydrogenation catalyst).
Tanx for advice.
