Metal-free intermolecular C–O cross-coupling reactions: synthesis of N-hydroxyimide esters

Abstract

Selectfluor-mediated intermolecular C–O cross coupling reaction for the synthesis of N-hydroxyimide esters was developed for the first time. The reaction is applicable to the coupling of readily available aryl and alkyl aldehydes with N-hydroxyphthalimide (NHPI) and N-hydroxysuccinimide (NHSI). The resulting active esters can be directly converted into amides in one pot.
