New Reactivity of Oxaziridine: Pd(II)-Catalyzed Aromatic C–H Ethoxycarbonylation via C–C Bond Cleavage
摘要:
A novel Pd(II)-catalyzed aromatic C-H ethoxycarbonylation with oxaziridine involving C-C bond cleavage is described. Various aromatic 2-phenylpyridines and related compounds as well as aryl ureas can be effectively ethoxycarbonylated. A catalytic cycle involving Pd(II) and Pd(IV) is proposed.
