General procedure: To AgNO3 (0.025g, 0.15mmol) solution in MeOH (20ml) in dark and stirring condition, 1,3-bis(diphenylphosphino)propane (dppp) (0.0605g, 0.15mmol) was added and stirred for 1h. Then L (0.0368g, 0.15mmol) was added to this solution and was magnetically stirred for 2h. Light yellow solution was obtained. It was filtered and kept undisturbed for crystallisation., 19845-69-3

The synthetic route of 19845-69-3 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.19845-69-3,1,6-Bis(diphenylphosphino)hexane,as a common compound, the synthetic route is as follows.

General procedure: A mixture of the dimeric complex [Pd(mu-Cl)(Cl)(NHC)]2(0.10 mmol) and the appropriate diphosphine ligand (0.10 mmol) was dissolved in CH2Cl2 (5.0 mL) and stirred at ambient temperature overnight. The reaction mixture was filtered over Celite, the solvent was reduced under vacuum to about 1.0 mL and the yellow precipitate formed by careful addition of n-hexane (c.a. 10 mL). The yellow solid was then filtered off, washed with n-hexane, and dried under vacuum.

The synthetic route of 19845-69-3 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.19845-69-3,1,6-Bis(diphenylphosphino)hexane,as a common compound, the synthetic route is as follows.

General procedure: [Cu(MeCN)4]ClO4 (0.025g, 0.076mmol) was taken in a double neck Round Bottom flask dissolved in dry MeOH by magnetic stirring under N2 atmosphere. Then 1,3-bis(diphenylphosphino)propane (dppp) (0.0314g, 0.076mmol) was added to this solution and stirred magnetically. After half an hour L (0.019g, 0.076mmol) was added to the reaction mixture and stirred for another 2h. The solution colour turned to red. It was filtered and kept undisturbed for crystallisation.
