    • 191 we further investigated the following reaction: 10% Pd/C (50mg) was stirred at room temperature in H2O (20 mL) under H; atmosphere for 24 h. and the Pd/C was collected by filtration and dried at room temperature under reduced pressure for 24 h. The H/D exchange reaction of la (50mg, 0.25 mmol) with the resulting dry Pd/ C (5.0mg. 10% of the weight of la) proceeded similarly (see Supporting Information. S106 and S107, The result indicated the following possibilities: 1) H2 remained on the Pd/C surface after a 24 h of drying under reduced pressure because of tight Pd-H, binding: 2) increase in the fraction of Pd0 by reduction of Pd (11)(22) which is contained in commercial Pd/C, under the hydrogenation conditions led to the acceleration of the H/D exchange reaction
