The synthesis and characterization of [M(Bu3P+etpE)Br](BF4)2 (where M = Ni or Pd and Bu3P+etpE = [(Bu3PCH2CH2)P(CH2CH2PEt2)2]+) and [M(etpPBu3+)Br]Br(BF4)4 (where M = Ni or Pd and etpPBu3+ = PhP[CH2CH2P(CH2CH2PBu3)2]2}4+) are described. The structure of [Ni(etpPBu3+)Br]Br(BF4)4 has been determined by X-ray diffraction. Treatment of [Pd(Bu3P+etpE)Br](BF4)2 with AgBF4 in acetonitrile produced [Pd(Bu

A new water-soluble triphosphine PhP[CH2CH2P-(CH2OH)2]2 is produced via the formylation of PhP(CH2CH2PH2)2; this triphosphine, upon interaction with [Rh(cod)Cl]2 and Pt(cod)Cl2(cod = cycloocta-1,5-diene) under biphasic (water/CH2Cl2) conditions, produced water-soluble rhodium(I) and platinum(II) complexes respectively; 31P and 195Pt NMR spectroscopic data confirm the tripodal coordination of RhI and PtII involving > PPh and the two –P(CH2OH)2 functionalities.
