1,1′-Bis(diphenylphosphino)ferrocene (dppf) (0.554 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 in dark at room temperature.The resultant suspension was refluxed with stirring under nitrogen atmosphere for 24 h. Slowly, the colour of the solution changed from light orange to dark yellowish orange. The resulting solution was evaporated to dryness to give a yellowish orange solid which was then extracted with dichloromethane (20 mL). The addition of cyclohexane (250 mL) to this solution led to yellowish orange needle shaped diffraction quality crystals. These were separated and washed with hexane and dried. Yield: (1.116 g, 70 percent).Anal. Calc. for C77H68N3P4Ag3Fe2: C, 57.97; H, 4.27; N, 2.63. Found: C, 58.12; H, 4.45; N, 2.68.
