Abstract

The reaction of (bipy) PdMe2 (1)(bipy= 2, 2′-bipyridine) with molecular oxygen results in the formation of the palladium (II) methylperoxide complex (bipy) PdMe (OOMe)(2). The identity of the product 2 has been confirmed by independent synthesis. Results of kinetic studies of this unprecedented oxygen insertion reaction into a palladium alkyl bond support the involvement of a radical chain mechanism. Reproducible rates, attained in the ...
