With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1271-51-8,Vinylferrocene,as a common compound, the synthetic route is as follows.
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.
1271-51-8, As the paragraph descriping shows that 1271-51-8 is playing an increasingly important role.
