New homoleptic nickel(0) and palladium(0) complexes with a water-soluble ligand, 1,3,5-triaza-7-phosphaadamantane, were prepared and characterized by 1H, 13C, and 31P NMR spectra. The complexes, together with the known analogous Ni(0) and Pd(0) complexes with tris(hydroxymethyl)phosphine, were found to be catalysts for buta-1,3-diene oligomerization or telomerization with water in an aqueous biphasic system without a cosolvent or a modifier. Tetrakis[tris(hydroxymethyl)phosphine]nickel (7) preferentially catalyzes oligomerization (both linear and cyclic) in the first example of a nickel-catalyzed buta-1,3-diene oligomerization in an aqueous biphasic system. Palladium complexes give telomers or linear oligomers in quantitative yields. In the case of the triazaphosphaadamantane complex 4, high selectivity to octadienyl ethers (87%) was observed. High values of metal leaching into the product phase in these reactions suggest an easy extraction of starting or intermediate metal complexes caused by the fact that both monomer and products are good ligands for the metal complexes in this particular case.

Iodide Complex

The distribution behaviors of iodide complex of Cd (II) in the propyl-alcohol ammonium sulfate aqueous biphasic extraction system was experimentally investigated in this work. Cd (II) was found to be extracted from the propyl-alcohol phase due to its ion pair formation as CdI42-(PrOH2+)2 in the presence of NH4I and in HCL, and the associated extraction conditions were optimized. The experimental results indicated that cadmium can be efficiently extracted by the method, and an extraction rate of 99.1% for cadmium can be achieved under optimizing conditions.

Water Soluble Complex

A water-soluble pigment excreted from Serratia marcescens has been purified by precipitation with ammonium sulphate, dialysis, and ultracentrifugation at different pH values. The purified pigment showed a single band in the ultracentrifuge and by electrophoretic analysis at several pH values. An average molecular weight of 5 × 106 was calculated from light-scattering measurements. This pigment is composed of carbohydrate and protein combined with prodigiosin, and several properties of the complex are described.
