Abstract The reaction of phosphinite Me2NCH2C C(CH2)2OP(i-Pr)2 (2) with Li2PdCl4 in methanol at room temperature affords the air and water stable mixedpincerpalladacycle (Me2NCH2(Cl)C C(CH2)2OP(i-Pr)2-κNκCκP)PdCl (3) whose structure has been ascertained by means of an X-ray diffraction study. This pincerpalladacycle is a highly efficient catalystprecursor for the coupling of aryl boronic acids
