Remarkably High Reactivity of Pd(OAc)2/Pyridine Catalysts: Nondirected C[BOND]H Oxygenation of Arenes -


Less is more: The rational optimization and general applicability of the catalytic system Pd(OAc)2/pyridine is described (see scheme). The catalyst shows excellent reactivity in the C[BOND]H oxygenation of simple aromatic substrates. The Pd/pyridine ratio is critical as the use of 1 equivalent of pyridine per Pd center leads to dramatic enhancements in both reactivity and site selectivity in comparison to Pd(OAc)2alone.
