I need a mechanism for hydrogenation of benzyl ester with Pd/C as catalyst. The reaction is performed at room temperature for 1h under pressure of H2, p=50 psi. Catalyst as a precipitate needs to be removed and washed with MeOH/H2O (1/1). I suppose a insertion of palladium occur, oxidative addition, and Pd is oxidized to Pd(II), and then a H2 is coordinated to Pd(II). The products are toluene and carboxylic acid. This is the reaction:

Your proposed mechanism is correct as far as I know.
