Benzyl alcohol linkers, such as those described in Section 3.1.1.1, can also be cleaved by palladium-catalyzed hydrogenolysis. Carboxylic acids have, for example, been obtained by hydrogenolysis of insoluble benzyl esters with Pd(OAc)2/DMF/H2 [89,161]. Resin-bound benzylic carbamates [162,163] and amides [164] can also be released by treatment with Pd(OAc)2 in DMF in the presence of a hydrogen source, such as 1,4-cyclohexadiene or ammonium formate. These reactions are quite surprising, because they require the formation of metallic palladium within the gelated beads. [Pg.54]
