With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.12150-46-8,1,1-Bis(diphenylphosphino)ferrocene,as a common compound, the synthetic route is as follows.
To a dichloromethane solution (15 cm3) of dppf (189 mg, 0.34 mmol), a methanolic solution of Na2PdCl4 (100 mg, 0.34 mmol) was added with continuous stirring. The resulting reaction mixture was refluxed for 8 hours. The solvents were evaporated in vacuo and the residue was washed thoroughly with diethyl ether to remove excess phosphine. The residue was extracted with dichloromethane, filtered and passed through a Florisil column. The resulting solution on refrigeration at ?5 oC afforded reddish orange crystals.(yield 214 mg, 86percent). Anal. Calcd. for C34H28P2FePdCl2?: C, 55.81?; H, 3.86?percent. Found: C, 55.86; H, 3.85?percent. 1H NMR (CDCl3) delta: 4.26 (br, 4H, C5H4), 4.71 (br, 4H, C5H4), 7.41-7.49 (m, Ph), 7.56-7.82 (m, Ph); 31P{1H}NMR (CDCl3) delta?: 34.1 ppm.
The synthetic route of 12150-46-8 has been constantly updated, and we look forward to future research findings.
