Abstract

The complex (Me3tacn)PdII(CH2CMe2C6H4) is readily oxidized by O2 or H2O2 to yield the PdIV-OH complex [(Me3tacn)PdIV(OH)(CH2CMe2C6H4)]+. 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.
