Different from the conventional synthesis methods and substrates, we designed a brand new method for synthesizing amides with platinum nanowires as catalysts and tert-butylhydroperoxide (TBHP) as the oxidant. Influence of factors, such as the catalyst, solvents, and the reaction temperature, were studied to determine the optimal reaction conditions. In addition, we explored the substrate generality

synthesize secondary and tertiary amides using O2 or air as an amide oxygen source. Radical scavenging studies disclosed that the cleavage of C−CN bond may proceed via an anionic pathway. The practicality of the work was also demonstrated through an in situ generated α-aminonitriles from corresponding aldehydes and amines to afford amides. The important features of this work include broad functional group

present work provides a general protocol with high levels of step- and atom-economy for the synthesis of aryl ethers, particularly for aryl benzylethers. The direct use of toluene and phenols as starting materials also renders this protocol as a novel strategy for the protection of hydroxylgroups presented in various phenols.
