  Tandem conversion of aldoximes to N‐methylated amides with methanol in presence of a single Ru(II) catalyst is accomplished through the Ru(II)‐mediated rearrangement followed by the reductive N‐methylation. Employing this protocol, several aldoximes were directly transformed to the N‐methylated amides using methanol. Kinetic experiments with H218O advocated that the aldoxime is acted as the nucleophile
