| Abstract: | reaction: see text] The nucleophilic substitution of benzylic carbonates with sodium arenesulfinates was catalyzed by the palladium complex generated in situ from Pd(eta(3)-C(3)H(5))Cl](2) and DPEphos bis(2-diphenylphosphinophenyl)ether]. The catalytic reaction proceeded in DMSO at 80 degrees C and gave a variety of benzylic sulfones in high yields. |
