Procedure: 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
