Cp 2 Fe-Mediated Electrochemical Synthesis of Phosphorylated Oxindoles and Indolo[2,1- a ]isoquinolin-6(5 H )-ones.

An efficient and environmentally friendly electrochemical synthesis of phosphorylated oxindoles and indolo[2,1- a ]isoquinolin-6(5 H )-ones mediated by readily available Cp 2 Fe has been developed, which illustrated a broad substrate scope and diverse functional group compatibility. This protocol featured an external oxidant-free process and was at room temperature, which was proposed to be driven by the anodic oxidation of Cp 2 Fe.
