Considering the synthetic relevance of heteroarenes in various areas ranging from organic synthesis to medicinal chemistry, developing practically simple methodologies to access functionalized heteroarenes is of a significant value. Described herein is an efficient approach for C-H silylation and hydroxymethylation of pyridines and related heterocycles by the combination of silanes or methanol with readily available N-methoxypyridinium ions with a low catalyst loading (2 mol %) under blue light irradiation. The synthetic importance of the developed reactions is demonstrated by the synthesis of biologically relevant compounds. Electron paramagnetic resonance spectroscopy, quantum yield measurements, and density-functional theory calculations allowed us to understand reaction mechanisms of both photocatalytic reactions.
