    摘要: The present invention relates to a metal complex of the general formula M(L)n, wherein each L is independently selected and represents a ligand and at least one L is vitamin B12 (cyanocobalamin) or a derivative thereof bound through the nitrogen atom of its cyanide group to M, which is an element selected from the transition metals, thus, forming a M-NC—[Co] moiety with [Co] representing vitamin B12 without cyanide and wherein n is 1, 2, 3, 4, 5 or 6. The complex can be prepared by mixing a precursor molecule with vitamin B12. The metal complexes can be used for radiodiagnostics, chemotherapy and radionuclide therapy.

    摘要: There is provided a process for preparing a lithium amide composition in which in a first step lithium metal is brought into contact with ammonia to form lithium bronze and in a second step the lithium bronze is reacted with a 1,3-diene or an arylolefin, such as butadiene, isoprene, piperylene, dimethylbutadiene, hexadiene, styrene, methyl styrene, divinylbenzene, naphthalene or anthracene, in the presence of a solvent wherein the temperature is maintained at or below the boiling point of ammonia. Examples of solvents include pentane, cyclopentane, hexane, heptane, octane, cyclohexane, toluene, xylene, cumene, ethyl benzene, tetraline, diethyl ether, tetrahydrofuran (THF), 2-methyl-THF, tetrahydropyran, diisopropyl ether, dibutyl ether, dioxan, methyl-tert-butyl ether or glycol ether. Lithium amide compositions obtainable by said process show improved activity, particularly in reactions involving enolate formation.
