Hey bees! Swic has been contemplating using a catalytic hydrogenation to reduce good old 2,5 DMNS. He read a great patent on Rhodium's site using Pd/BaSO4 as a catalyst, but was wondering if any bees see a problem with using straight PtO2 as the catalyst. Also, instead of GAA as the solvent, he seems to remember KrZ stating that an ethyl acetate/GAA mix would help increase solubility of the nitrostyrene, anybody care to agree/disagree?
As an on the side question, swic wanted to know if anyone could help him understand something he read. He was reading into some 'modified catalyts' and came across the Lindlar catalyt. As he continued to read he saw that this catalyt is configured to only perform a sort of partial hydrogenation (The example is for the synthesis of cis alkenes). From what he has understood Pd/C and PtO2 are used for complete saturation, and not a partial saturation, correct? Thanks.
