Grapheneoxide was found to be a highly efficient and cost-effective heterogeneous catalyst for the direct metal-free transformation of quinoline and isoquinoline N-oxides into the corresponding nitriles under mild conditions. This method is simple, economic and environmentally benign, representing a useful strategy for the convenient synthesis of α-cyano N-oxides that are difficult to prepare by

hydrogen-bonded ethanol (the formation of a singlet hydrogen-bonded radical ion pair). Thus, the new type of magnetic-field effect was excellently explained in terms of an electron-nuclear hyperfine interaction mechanism including the electron-exchange interaction in the radical-ionpair (the magnetic-field effect due to HFI-J mechanism). This implies that the magnetic-field effect is unambiguous evidence
