Abstract

Procédé de préparation de caroténoïdes symétriques à partir des sels de phosphonium des moitiés de molécule de ces caroténoïdes symétriques. On soumet les sels de phosphonium des moitiés de molécule à une oxydation électrochimique dans un solvant en présence d'une base, ce qui provoque la dimérisation des moitiés de molécule avec décomposition de l'oxyde de phosphine substitué.
