反応条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 2.46 g (10 mmol) of 1,3-bis(hydroxymethyl)ferrocene and 4.72 g (40 mmol) of diisopropylphosphine were added to 40 ml of acetic acid. The resulting mixture was heated at 80° C. for 3.5 hours and extracted with benzene after cooling. The organic phase was then washed with water and then dried over Na2SO4. After evaporation an orange residue was chromatographed on an alumina column. Elution with an ether-light petroleum mixture yielded 3.92 g (88%) of the product. Selected NMR data (CDCl3, 22° C.) 1H: δ0.92 (m, 24H, CH3), 1.63 (m, 4H, CH(CH3)2), 2.49 (bs, 4H, CH2P), 3.92 (s, 5H, C5H5), 3.95 (bs, 2H, 4.5-H), 4.06 (bs, 1H, 2-H). 31P NMR (CDCl3, 22° C.): δ 10.97(s, 2P). extracted with benzene after cooling The organic phase was then washed with water dried over Na2SO4 After evaporation an orange residue was chromatographed on an alumina column Elution with an ether-light petroleum mixture

実験手順: stirring bar was added 6-chloromethyl-2,2′-bipyridine (BPy-CH2Cl) (1.03 g, 5.00 mmol), di-iso-propyl phosphine (710 mg, 6.00 mmol), and 15 mL MeOH in nitrogen glove box. The flask was sealed and heated at 50° C. for 48 hrs with stirring outside the glove box. After cooling, it was reintroduced to the glove box, triethylamine (910 mg, 9.00 mmol) was added and the reaction mixture was stirred at room temperature for 1 hr. The solvents were removed under reduced pressure to obtain a white solid. The residue was washed with ether (2×10 mL), filtered and was removed under reduced pressure to yield a pale yellow liquid. It was further purified by basic alumina chromatography under the glove box using hexane as an eluent to yield pure 6.
