many as 13double bonds have been isolated by column chromatography on silica gel under dinitrogen at minus}40degree}C and characterized by sup 1}H and sup13}C NMR and UV-vis studies. The 17-ene has been observed by HPLC. Polyenes containing more than 17 double bonds are relatively unstable under the reaction and subsequent isolation conditions; those containing between 11 and 15 double bonds decompose
