Electrochemical NHPI catalyzed addition of a-alkoxy radicals to oxime ethers
In this work, we describe how N-hydroxyphthalimide (NHPI), also under catalytic amounts, promotes hydrogen atom transfer (HAT) from alcohols under electrochemical conditions through the generation of phthalimide-N-oxyl (PINO). In contrast with the well-known electrochemical oxidation to their corres...

| Resumo: | In this work, we describe how N-hydroxyphthalimide (NHPI), also under catalytic amounts, promotes hydrogen atom transfer (HAT) from alcohols under electrochemical conditions through the generation of phthalimide-N-oxyl (PINO). In contrast with the well-known electrochemical oxidation to their corresponding aldehydes or ketones, α-alkoxy radicals were successfully coupled with oximes promoting a carbon–carbon bond-forming event. This method allows the α-functionalization of primary and secondary alcohols under simple, straightforward, and mild electrochemical reaction conditions in a single operation even in the presence of catalytic amounts of the HAT catalyst |
