Multistep Reversible Redox Systems, XXXIV. - Polyenes as Four-Step Redox Systems: Synthesis and Spectroscopy
Hagenbruch, Bernd,Huenig, Siegfried
, p. 340 - 353 (2007/10/02)
The synthesis of the pentaenes 2.0-4.0 and of the polyenes 2.1-2.4 is described.All alkenes carry rigid, cross-conjugated end groups.The Dienone 6, the polyene aldehydes 18 and 19 as well as the phosphorous ylid 22 serve as crucial intermediates. 1H NMR and UV/VIS spectra of all polyenes are discussed.
