A Pd-catalyzed Suzuki cross-coupling of arylboronic acids with Yagupolskii-Umemoto reagents was explored. In contrary to trifluoromethylations, the Pd-catalyzed reaction of R−B(OH)2 and [Ar2SCF3]+[OTf]− provided the arylation products (R−Ar) in good to high yields. The reaction confirms that the S−Ar bonds of [Ar2SCF3]+[OTf]− can be readily cleaved in the presence of Pd complexes. The relatively electron-poor aryl groups of asymmetric [Ar1Ar2SCF3]+[OTf]− salts are more favorably transferred compared to the electron-rich ones. This reaction represents the first report of utilization of [Ar2SCF3]+[OTf]− as arylation reagents in organic synthesis. [ABSTRACT FROM AUTHOR] |
