Yield:626-58-4 99%
Reaction Conditions:
with hydrogen in water at 100; under 15001.5 Torr; for 7.5 h;
Steps:
3.2. Hydrogenation reaction in aqueous phase
General procedure: To showcase the applicability of this novel catalyst, the hydrogenationwas utilized for the other N-heterocyclic compounds. Asshown in Table 4, the hydrogenation of pyridine and 4-methylpyridinecould afford the desired product in excellent yield without by-products(Table 4, entries 1 and 2) although the reactivity of 4-methylpyridinewas somewhat less than that of pyridine, and a slightly longer reactiontime (7.5 h) was needed for full conversion (Table 4, entry 2). Additionally,indole was entirely transformed to dihydroindole and quinolinewas completely converted to 1,2,3,4-tetrahydroquinoline withhigh selectivity, respectively (Table 4, entries 3 and 4).
