1271-51-8, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Vinylferrocene, cas is 1271-51-8,the iron-catalyst compound, it is a common compound, a new synthetic route is introduced below.
General procedure: In a 25-mL round-bottomed flask, a mixture of aryl iodide (5 mmol), alkene (6 mmol), and base (5.6 mmol) was placed in 4 mL of DMF, then a solution of the complex 3 (0.005 mol percent) in 1 mL of DMF was added. The reaction mixture was refluxed for the time stated in Tables 3 and 4 at 140 ¡ãC. The reaction mixture was poured into water (20 mL) and extracted with ether or hexane (2¡Á30 mL). The combined organic layers were dried over anhydrous sodium sulfate. After the removal of the solvent in vacuo, the resulting crude was purified by column chromatography on silica gel (hexane/ethyl acetate) to give the corresponding cross-coupling product (the purified product was identified by means of determination of mp and by 1H and 13C NMR, the data obtained are consistent with literature).26 The entire flasks used in the each coupling reaction were meticulously cleaned with aqua regia to avoid the presence of unseen palladium catalyst.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Vinylferrocene, 1271-51-8
