Synthesis and structural characterization of the first unsymmetrical diarylpalladium complex trans-Pd(C_6F_5)(2,4,6-C_6F_3H_2)(PEt_3)_2, derived from transmetallation between 2,4,6-trifluorophenylboronic acid and trans-Pd(C_6F_5)I(PEt_3)_2

摘要

The reactions of 2,4,6-trifluorophenylboronic acid with aryl(iodo)palladium(II) complexes, trans-Pd(C_6F_5)I(PR_3)_2 (PR_3 = PEt_3, PMe_2Ph, PMePh_2) in the presence of Ag_2O afforded trans-Pd(C_6F_5X2,4,6-C_6F_3H_2)(PR_3)_2 which are stabilized by fluorine atoms in the ortho positions.
