We report methylations of alcohols and anilines catalyzed by DMF-stabilized Ir nanoclusters using methanol as the C1 source. The DMF-stabilized Ir nanoclusters were prepared in one step and have diameters of 1–1.5 nm. They react in a borrowing-hydrogen reaction and are efficient methylation catalyst...
