A radical mediated C–H direct formylation of N-heteroarenes with methanol is reported. The reaction features a novel iron-catalyzed Minisci oxidative coupling process using commercially available methanol as a formylating reagent. It effectively solved the long-standing problems associated with using methanol as a formylating reagent in these types of reactions. Compared to the traditional Minisci

An efficient metal-free protocol has been developed for the sp(3) C-H bond oxidation of 2-methylquinolines in the presence of PIDA under microwave irradiation, providing 2-quinolinecarboxaldehydes with moderate to high yields and excellent selectivities. A wide range of 2-quinolinecarboxaldehydes with different functional groups have been synthesized. A tentative mechanism has been presented to explain this highly selective oxidation process.
