Intramolecular electron transfer in the intermediately formed radical-anion during electroreduction of ethyl 3,7-dimethyl-10-oxo-2,6-decadienoate in DMFA

Abstract

1. The polarographic behavior of the four isomers of ethyl 3,7-diraethyl-10-oxo-2,6-decadienoate and also of model compounds (heptenal and 2E,6Z-farnesenic ester) was studied. During electroreduction intramolecular electron transfer from the ester groups to the aldehyde group occurs in the intermediately formed radical-anion. 2. The existence of the conformation with closer aldehyde and carboxyl groups in the α,ω-aldehydo esters (I) was confirmed by the polarographic method.
