A reusable palladium/cationic 2,2′-bipyridyl system-catalyzed double Mizoroki-Heck reaction in water was written by Chen, Yu-Chi;Wu, Chien-Chi;Liao, Wei-Ting;Liu, Ling-Jun;Tsai, Fu-Yu. And the article was included in Catalysts in 2017.Product Details of 5460-32-2 This article mentions the following:
A reusable PdCl2(NH3)2/cationic 2,2′-bipyridyl system was used to catalyze the double Mizoroki-Heck reaction of aryl iodides with electron-deficient alkenes in water in the absence of inert gas, giving U+03B2,U+03B2-diarylated carbonyl derivatives in good to excellent yields. The formation of unsym. U+03B2,U+03B2-diarylated alkenes were also studied by coupling aryl iodides with the corresponding aryl-substituted U+03B1,U+03B2-unsaturated carbonyl compounds This water-soluble catalyst can be swiftly separated from the organic layer using simple extraction for the further reuse, and, thus, makes it an operationally-simple and environmentally-benign procedure. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Product Details of 5460-32-2).
4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I.Product Details of 5460-32-2
