activation of aldehydes and thiazoles is developed. The reaction occurs smoothly, under metal-, acid- and solvent-free conditions usingtert-butylhydroperoxide as the oxidant under an air atmosphere, to afford a wide range of heteroaryl ketones in moderate to good yields. The sp2 C–H bonds in the aldehyde and thiazole undergo directoxidativecross-coupling, resulting in C-2 acylation of the azole
