Abstract

{The new oligophosphines [H2P(CH2)(2)](2)PH, [H2P(CH2)(2)P(H)CH2](2), and {[(H2P(CH2)(2)](2)PCH2}(2) have been made by hydrophosphination of diethyl vinylphosphonate (2) with H2P(CH2)(2)PH2 (1), using different ratios of 2/1, followed by LiAlH4 reduction of the phosphonate intermediates; the three phosphonate precursors were obtained as oils of varying purity (similar to 90-95%) in low (similar to 20%) to almost quantitative yield. The tri-, tetra-, and hexaphosphines were then treated with formaldehyde in the presence of hydrochloric acid to generate the corresponding water-soluble (hydroxymethyl)phosphonium chlorides {(HOCH2)(3)P[(CH2)(2)P(CH2OH)(2)](n)(CH2)(2)P(CH2PH)(3)}Cl-m (n = 1
