    • To our knowledge, this is the first example of the application of microwave heating to the direct arylation of pyridine N-oxide, although Kappe et al. have recently reported the microwave-promoted direct arylation of electron-rich heterocycles with aryl and heteroaryl halides M.

    • Although the reasons for this are unclear, microwave heating has been reported to give better yields, reduce side reactions and improve reproducibility in certain cases. For a review see C.O. Kappe Angew. Chem., Int. Ed. 43 2004 6250
