- W2070810672 abstract "La réduction électrochimique de la phényl-1 diméthyl-4,4 pentène-1, one-3 est réalisée en milieu aprotique (DMF) sur cathode de mercure, en présence de chlorures métalliques (Li+, Cr2+, Fe2+, Mn2+, Co2+, Zn2+, Ni2+). Il y a hydrodimérisation sélective, avec d'excellents rendements, soit en ε dicétone racémique, soit en cétol cyclopentanique et absence totale de polymérisation. Une interaction acido—basique entre la cétone et le cation métallique agissant comme acide de Lewis est postulée. The electrochemical reduction of 1-phenyl 4,4-dimethyl pentene 3-one can be achieved in an aprotic medium (DMF) on a mercury pool cathode, in the presence of metallic chlorides (Li+, Cr2+, Fe2+, Mn2+, Co2+, Zn2+, Ni2+). There is selective hydrodimerization, with very high yields, either into ε racemic diketone or cyclopentanic ketol with total lack of polymerization. An acid—basic interaction between ketone and metallic cation, acting as Lewis acid, is postulated." @default.
