This paper studies the interaction of Pd(0) complexes with the formulas Pd(Ph/sub 2/PC/sub 6/H/sub 4/F)/sub 2/ (PPh/sub 3/) (I), Pd(Ph/sub 2/PC/sub 6/H/sub 4/F)/sub 2/ (AsPh/sub 3/) (II), and Pd(Ph/sub 2/PC/sub 6/H/sub 4/F)/sub 2/ (SbPh/sub 3/) (III) with oxygen. The typical ESR signal is presented which appears when the complexes are oxidized by oxygen. On the basis of the ESR and XPS data it has been shown that the formation of the paramagnetic compounds occurs as a result of the oxidation of the Pd(0) complexes and the appearance of Pd(I)-O/sub 2//sup -/ adducts, in which the paramagnetic electron is localized predominantly in the oxygen pi orbitals. The interaction of Pd(0) complexes of the type PdL/sub 2//sup 2/L/sup 1/ with oxygen in the solid phase results in the formation of the corresponding phosphine oxides and dimeric palladium compounds.
