Photocatalytic Csp2‐H Amination of Hydrazones with N‐Aminopyridinium Salts

The current approach describes Csp2‐H amination of aldehyde‐derived hydrazones via nitrogen centred radical generation from N‐aminopyridinium salts under photocatalytic condition. The scope of reaction is wide in terms of both the substrates and most of the products were isolated in good yields furnishing Z‐isomer exclusively. Further, aminated hydrazones were hydrolyzed to give amides resulting into indirect Csp2‐H amination of aldehydes.
