Abstract: A one pot method is provided for preparing an (octyloxyphenyl) phenyliodonium tosylate and the corresponding hexafluorometalloid salt. n-Octylphenyl ether is initially prepared using a halooctane and phenol in the presence of a phase transfer catalyst followed by the addition of iodobenzene, a peracid, and p-toluene sulfonic acid. The resulting (octyloxyphenyl)phenyl iodonium tosylate can be directly metathesized after an optional treatment step with an alkali metal hexafluoroantimonate salt. The (octyloxyphenyl)phenyl iodonium hexafluorometalloid salt can be used as a photoinitiator for UV curable organic materials such as epoxy resins.

Abstract: A complex of a tetradentate tetraanionic ligand L of the formula: ##STR1## and a metal, preferably a transition metal, is described where Z is an anionic oxidation reistant metal complexing group, Ch is an oxidation resistant chelate group containing 1 to 4 chain atoms and Y is hydrogen. The chelate and ring Z-Ch-M-Z functional groups Z, such as N or O, are resistant to oxidation and the ring contains 4 to 7 preferably 5 to 6 chain atoms. An osmium complex containing two pyridine ligands is an oxidation catalyst. Further activation by anodic oxidation and heating to a temperature exceeding 30.degree. C. greatly increases catalytic activity.

Abstract: A method for preparing a coordination complex of an isonitrile ligand and radionuclide such as Tc, Ru, Co, Pt, Fe, Os, Ir, W, Re, Cr, Mo, Mn, Ni, Rh, Pd, Nb and Ta is disclosed. The method comprises preparing a soluble metal adduct of said isonitrile ligand by admixing said ligand with a salt of a displaceable metal having a complete d-electron shell selected from the group consisting of Zn, Ga, Cd, In, Sn, Hg, Tl, Pb and Bi to form a soluble metal-isonitrile salt, and admixing said metal isonitrile salt with a salt comprising said radioactive metal in a suitable solvent to displace said displaceable metal with the radioactive metal thereby forming said coordination. The complex is useful as a diagnostic agent for labelling liposomes or vesicles, and selected living cells containing lipid membranes, such as blood clots, myocardial tissue, gall bladder tissue, etc.
