An optimal selection of the oxidizing agent goes hand in hand with the insight into the reaction mechanism. This review covers recent advances in methods of direct oxidative C-H functionalization of azines and their derivatives with heteroaromatic nucleophiles. Also we review the data on application of inorganic and organic oxidants for implementation of these reactions. C-H functionalizations under electrochemical and photocatalytic oxidation conditions are included as well. |
