Cyclopentadienyl metal complexes for positron-emission tomography: Cyclopentadienyl metal complexes for positron-emission tomography. Wenzel, Martin (Germany ). Ger. Offen.In this study， 131220-74-1 and 138979-05-2 are also used. DE 4015250 A1 14 Nov 1991,7 pp. (Germany). CODEN: GWXXBX. CLASS: ICM: A61K049-02. ICS: C07F013-00; C07F015-00; C07F017-00; C07D453-02. APPLICATION: DE 90-4015250 9 May 1990. DOCUMENT TYPE: Patent CA Section: 8 (Radiation Biochemistry) Cyclopentadienyl complexes having positron-emitters as central atoms, are prepd. as PET radiodiagnostic agents. Preferred are metallocene derivs. or cyclopentadienyl-carbonyl compds. of the cymantrene type. The central atoms are metals of the 7th or 8th subgroup of the periodic table, preferably, 52Mn, 52Fe, 95Ru or 58Co. A mixt. of 8 g ferrocenaldehyde, 5.83 g quinuclidinone-HCl, 3.5 g KOH and 15 mL day MeOH was stirred for 120 h, to give 2-ferrocenylidine quinuclidin-3-one, which was reduced with NaBH4 to 2-ferrocenylidene quinuclidin-3-ol. This (6 mg) was heated with 1 mg RuCl3-H2O, 0.1 mCi 103RuCl3 and 0.2 mL MeOH contg. 3% HCl to give a mixt. of ferrocene and ruthenocene mono- and di-Me ethers. Ruthenocene di-Me and di-Et ethers showed high cardiac affinity in rats, whereas the mono-Me ether showed high brain affinity. .

R = 0.016 For 1389 unique reflections. 1,4-(1,1'-Ruthenocenediyl)butane (II) is monoclinic, space group P21/c, with a 11.997(3), b 12.718(2), c 7.725(2) ?, and b 107.03(2)°; d.(exptl.) = 1.66(2) and d.(calcd.) = 1.68 for Z = 4; R = 0.033 for 2025 unique reflections. The cyclopentadienyl (Cp) rings have eclipsed conformation and the dihedral angles between them are 14.8(2) and 1.7(2)° for I and II, resp. The C-C-C angles in the C chain connecting the 2 Cp rings are 114.5(3)-116.7(3)°, showing slight strain in this bridge.
