摘　　要：1 Introduction A variety of Pd(Ⅱ)-catalyzed oxidative transformations ot allcenes with oxygen nucleophiles are catalyzed by PdX_(2)(X=OAc,Cl,etc)with CuX_(n)(n=1 or 2)under O_(2).In the so-called Wacker catalyst of such,Pd(OAc)_(2) is less reactive compared to PdCl_(2).In an attempt to increase the reactivity of Pd(OAc)_(2),we have now found that tuning of Cu site with catechol gives an intriguing reactivity to Pd(OAc)_(2),which is unprecedented in the chemistry of palladium.
