Deuterium labeling study on Rh(I)- catalyzed hydrodecarboxylation.

aGeneral conditions: ArCO2H (0.225 mmol,1 equiv), [(cod)Rh(OH)]2 (0.015 equiv), DPPP (0.030 equiv), Na2CO3 (1.0 equiv), toluene-H2O (1.50/0.25 mL), 120 °C, 30 h; isolated yields; >90% deuterium transfer by NMR analysis. bD2O was used in place of H2O.
