Abstract

Des substrats organiques, tels que des éthers cycliques, des amides à substitution N, des cétones, des composés alkylaromatiques et des composés alkylhétéroaromatiques peuvent être alcoxylés, en particulier méthoxylés, de manière anodique en présence d'un alcool. L'alcoxylation en présence d'un médiateur ou dans une cellule divisée avec un électrolyte solide est connue. L'alcoxylation selon la présente invention se produit en présence d'un médiateur dans une cellule d'électrolyse non divisée, à l'aide d'une anode à couche de diamant ou d'une anode en or. On obtient ainsi des rendements élevés en matières et en courant.
