This paper presents the synthesis of a series of push-pull and quadrupolar π-conjugated structures incorporating pro-aromatic methylenepyran electron-donor groups and various electron-attracting groups. Some of the methylenepyran derivatives were oxidized by I2 to give, after reduction by Na2S2O3, bismethylenepyran compounds via successive steps. The electrochem. redox properties of methylenepyrans 5-9 and extended bismethylenepyrans 10, 14, and 15 determined by cyclic voltammetry indicate the formation of redox bistable systems with high bi-stability. Oxidation of the dimers obtained from 5 to 9 was also described. All compounds are colored and slightly fluorescent (except some bismethylenepyran derivatives). Some compound second-order nonlinear optical properties were investigated, and large pos. values of μβ were obtained. A pos. dimer effect was also observed for bispyran derivatives In the experimental materials used by the author, we found 4-Iodo-6-methoxypyrimidine(cas: 161489-05-0Synthetic Route of C5H5IN2O)
4-Iodo-6-methoxypyrimidine(cas: 161489-05-0) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.Synthetic Route of C5H5IN2O
