Abstract

Reactivity towards p-methoxybenzaldehyde (ArCHO) of electrochemically generated phosphonate carbanions has been investigated. Electrolyses were carried out at a mercury cathode in DMF and two routes to the desired carbanion have been compared:(i) Deprotonation of phosphonates of general formula (EtO) 2P (O) CHYW (Y= W= Cl; Y= H, W= Cl; Y= Cl, W= CO2Et; Y= H, W= CO2Et; Y= CH3, W= CO2Et; Y= Cl, W= CH3), by the bases ...
