Abstract

An aqueous solution of (hydroxymethyl)triphosphine [(HOCH2)2P(CH2)2]2PCH2OH (II) was synthesized in situ by treatment of the triphosphine H2P(CH2)2PH(CH2)2PH2 with formaldehyde. Addition of a CH2Cl2 solution of trans-PdCl2(PhCN)2 to an in situ aqueous solution of II resulted in the formation of a species thought to be [PdCl{[(HOCH2)2P(CH2)2]2PCH2OH}]+Cl-. Attempts to isolate the complex were unsuccessful because of conversion to material containing small amounts of phosphine oxide(s) formed via a redox reaction involving water. The triphosphine trioxide [(HOCH2)2P(O)(CH2)2]2P(O)CH2OH was readily isolated from an in situ solution of II by treatment with aqueous H2O2.
