DPPF (55 mg, 0.1 mmol) was added to a rapidly stirred, 10 mlCH2Cl2 suspension of RuCl2(PPh3)3 (96 mg, 0.1 mmol). A colorchange from purple-black to red was observed within a few minutes.The solutionwas stirred for 30 min, then a CH2Cl2 solution of2-aminopyridine (9.4 mg, 0.1 mmol) was added, giving an immediatecolor change to yellow-green. After a further 30 min, thesolvent was removed in vacuo and 5ml of diethyl ether (Et2O) wereadded. The yellow product was filtered off, washed twice withether (2 5 ml), and then dried under vacuum. Yield: 73 mg (93percent).Anal. Calcd for C39H34Cl2N2P2FeRu: C, 57.07; H, 4.15; N, 3.41.
