Singlet oxygen oxygenation of enol ethers; the synthesis of optically active 1,2-dioxetanes. II

(+)-(Methoxymethylene)fenchane I (R = H, R1 = OMe) on singlet O oxidn. gave dioxetanes II and III, which on thermal decompn. underwent chemiluminescence in which (+)-fenchone was the only chemiluminescent species at lmax 420 nm. Photosensitized oxygenation of I (R = OMe, R1 = H) also gave 2 isomeric 1,2-dioxetanes. I were prepd. by Wittig methoxymethylenation of (+)-fenchone. Adamantanone (IV) on Wittig methoxymethylenation, followed by singlet O oxidn. gave dioxetane V, which on thermal decompn. gave only IV and HCO2Me and a bright blue chemiluminescence with lmax 420 nm and k1 2.96 * 10-3 s-1 at 79.9 Deg in decane. The prepn. of the dioxetanes allows the comparison of light- and chem. induced circular polarization of luminescence. [on SciFinder (R)

Method of manufacturing conductive heterocyclic polymers, new heterocyclic conductive polymers, new intermediate products for the preparation of the polymers, and synthesis of the intermediate products

The polymers are prepared by using the new intermediate product which forms a polymeric precursor, and which is converted into the desired heterocyclic polymer by ring closure
