Oligophosphaalkanes, VI. Syntheses and NMR Spectroscopic Characterization of PH-functional Methylene Bridged Diphosphanes R2P-CH2-PRH and HRP-CH2-PRH

1,3-Diphosphapropane, H2P-CH2-PH2 (1) was synthesized in about 40 percent yield by reduction of Cl2P-CH2-PCl2 with LiAlH4.The mono-, di-, and tri-substituted derivatives RHP-CH2-PH2 (R = iPr, CH2Ph, 3a, b) RHP-CH2-PHR (R = iPr, CH2Ph, tBu, 5a - c), R2P-CH2-PRH (R = Me, iPr, CH2Ph, 10b, 7a, b) are accessible using Cl2P-CH2-PCl2 as a starting material.A multiple stage synthesis based on MePCl2 affords the disecondary phosphane MeHP-CH2-PMeH (10d), which in contrast to reports given in the literature is thermally stable to at least 100 deg C.The 31P and 1H NMR spectra of 1 have been analyzed and simulated by use of computer programs.The structure of the phosphanes is discussed on the basis of their 1H, 31P, 31P, and 13C NMR spectra.
