Palladium on carbon encapsulated in POEPOP(1500): a resin-supported catalyst for hydrogenation reactions.

[reaction: see text] A new a versatile catalyst for hydrogenation reactions wherein palladium on carbon is encapsulated in POEPOP(1500)-resin is described. This polymer-supported catalyst has been successfully used in solution phase hydrogenation of a double and a triple bond as well as hydrogenolysis of a benzyl-protecting group. While the activity of the new catalyst is marginally lower than standard 10% Pd/C, it has the advantage of being reused several times without significant loss of reactivity.
