12150-46-8, 1,1-Bis(diphenylphosphino)ferrocene is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

In a nitrogen filled glove box, [(1tBuIndenyl)Pd(,1Cl)]2 (100 mg, 0.16 mmol) and 1,1?-bis(diphenylphosphino)ferrocene (DPPF) (177 mg, 0.32 mmol) were added to a 100 mL Schlenk flask. Methanol (20 mL) was added and the mixture was stirred at roomtemperature for 2 hours. During this time, the mixture became homogenous with a deep red color. The flask was opened to air and the solvent was removed with a rotary evaporator to yield a red oil. Pentane was added, followed by sonication; vacuum filtration produced a red crystalline solid (225 mg, 81percent).

A solution of of N-(5-bromo-pyridin-2-yl)-acetamide (4.30 g, 20 mmol) in acetonitrile (15 ml) and triethylamine (5.04 ml) was treated with palladium acetate (45 mg, 0.2 mmol) and tri-o-tolylphosphine (203 mg, 0.66 mmol). The mixture was placed in a pressure reactor under 50 psig of ethylene pressure and heated at 85C for 66 hours. The reaction mixture was cooled, vented, and partitioned between phosphate buffer (0.1 M, pH 6.6) and ethyl acetate. The aqueous phase was extracted with ethyl acetate twice more. The combined ethyl acetate extracts were washed with additional phosphate buffer, brine and dried over sodium sulfate. The extracts were filtered and evaporated to afford 2.06 g (63%) of the title product as a flaky crystalline residue. Recrystallization from ethyl acetate/cyclohexane gave colorless flakes. mp 120 – 121 C 1H NMR (CDCl3): delta = 8.55 (br, 1 H); 8.24 (d, 1 H); 8.15 (d, 1 H); 7.76 (d of d, 1H); 6.64 (d of d, 1 H); 5.73 (d, 1 H); 5.28 (d, 1 H); 2.19 (s, 3 H).
