146960-90-9, 1,1′-Bis(dicyclohexylphosphino)ferrocene is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
1,1′-Bis(dicyclohexylphosphino)ferrocene (dcpf) (0.578 g, 1.0 mmol) was added to a solution of silver(I) cyanide (0.134 g, 1.0 mmol) in 30 mL CH3OH:CH2Cl2 (50:50 V/V) mixture at room temperature. The resultant suspension was refluxed with stirring under nitrogen atmosphere for 24 h in dark. Slowly, the colour ofthe solution changed from light yellowish orange to dark yellowish orange colour. The resulting solution was evaporated to dryness to give a yellowish orange solid which was then extracted with dichloromethane (20 mL). The addition of diethyl ether (100 mL) to this solution led to yellow needle shaped diffraction quality crystals. These were separated and washed with hexane and dried. Yield: (0.846 g, 50 %). Anal. Calc. for C72H104N4P4Ag4Fe2: C, 51.06; H,6.15; N, 3.31. Found: C, 51.28; H, 6.34; N, 3.43.
