N-(pyridine-2-yl)amides in water from ketones and 2-aminopyridine via direct oxidative C–C bond cleavage has been developed. A series of ketones, including more challenging inactive aromaticketones substituted with diverse long-chain alkyl groups, were selectively converted to N-(pyridine-2-yl)amides. Furthermore, the protocol can be applied to aryl alkyl carbinols to afford the corresponding amides in moderate

Photoinitiated radical carbonylation with [11C]carbonmonoxide at low concentration was employed in syntheses of carbonyl-11C-labeled amides using alkyl iodides and amines as precursors. Eleven 11C-amides were synthesized in up to 74% decay-corrected radiochemical yields with reaction times of 400 s and with up to 95% conversion of carbonmonoxide. Starting with 26.3 GBq of [11C]carbonmonoxide, 10.6 GBq of

Abstract A novel and efficient method for the synthesis of amide has been developed. The reactions proceeded smoothly under aqueous conditions at room temperature and generated the corresponding products in good to excellent yields. It is worth noting that alkyl amines which did not react in known approaches are well tolerated in our system.
