Dioxygen activation by an organometallic Pd(II) precursor: Formation of a Pd(IV)-OH complex and its C-O bond formation reactivity

The complex (Me3tacn)PdII(CH2CMe 2C6H4) is readily oxidized by O2 or H2O2 to yield the PdIV-OH complex [(Me 3tacn)PdIV(OH)(CH2CMe2C 6H4)]+. Thermolysis of this product leads to the selective C(sp2)-O reductive elimination of 2-tert-butylphenol, no C(sp3)-O elimination product being detected. This system represents a rare example of selective C(sp2)-O bond formation that is relevant to Pd-catalyzed aerobic C-H hydroxylation reactions. The Royal Society of Chemistry.

Synthesis and insertion reactions of the cyclometalated palladium-alkyl complexes Pd(CH2CME2-o-C6H4)L2. Observation of a pentacoordinated intermediate in the insertion of SO2

Palladacycles of the type Pd(CH2CMe2-o-C6H4)L2, 2, have been synthesized by treatment of the corresponding chloroalkylcomplexes Pd(CH2CMe2C6H5)ClL2 (L2 = (PMe3)2, 2a, or 1,5-cyclooctadiene (cod), 2b) with suitable bases, or by simple ligand exchange reactions from the cyclooctadiene derivative 2b. The metallacycles 2 react with activated alkynes and with sulfur dioxide, giving rise to different insertion products.
