    Notes: Summary Reactions of 2-(dimethylaminomethyl)ferrocenyl-lithium ((FcN)Li,1) with various cerium(IV) precursors lead to the formation of heterobimetallic organocerium(III) complexes. The compounds Li3[(FcN)2CeF4(THF)3] (2), (FcN)2CeF(DME)2 (3), Li4[(FcN)CeCl6] (4), and Li[(FcN)CeCl3(DME)] (5) have been isolated by redox reactions. Similar treatment of (C5Me5)2 Ce(μ-Cl)2K(THF)2 with one equivalent of1 affords the neutral species (C5Me5)Ce(FcN)Cl (6)via displacement of one C5Me5 ligand. Complexes of the type (C5Me5)Ln(FcN)Cl have also been isolated forLn=Pr (7), Nd (8), and Sm (9). These and related heterobimetallic lanthanideFcN complexes have been studied by Mößbauer spectroscopy.

    Preparation and structural studies on organotin(IV) complexes with flavonoids (1998)

    Notes: Abstract Fourteen complexes of di-n-butyltin(IV)2+ cations with flavonoid glycosides (rutin, hesperidin, 2′,4′,3-trihydroxy-5′,4-dimetoxychalkone 4-rutinoside) and flavonoid aglycones (quercetin, morin, hesperitin and sorte flavones) were prepared. The composition of the complexes was determined by standard analytical methods. The results showed that complexes containing diorganotin(IV)2+ moiety and the ligand in 1∶1, 2∶1 or 3∶1 ratio are formed. The FTIR spectra were consistent with the presence of Sn-O (phenol or carbohydrate) vibration in the compounds. The structure of the complexes was measured by Mössbauer spectroscopy. Comparison of the experimental quadrupole splitting with those calculated on the basis of partial quadrupole splitting concept revealed that the complexes are of four types: with the central tin atoms surrounded by donor atoms in a purely trigonal-bipyramidal, octahedral+trigonal-bipyramidal, trigonal-bipyramidal+tetrahedral and octahedral+tetrahedral arrangement. This procedure also distinguished between the different structural isomers of both trigonal-bipyramidal and octahedral complexes. Conclusions could therefore be drawn on the factors determining which of the isomers are formed in the systems. The Mössbauer parameters obtained for organotin(IV)-flavonoid complexes were compared with those measured for organotin(IV)-carbohydrate complexes.

    Description / Table of Contents: Contributions to Organolanthanide Chemistry. II. On 2-(dimethylaminomethyl)ferrocenyl Compounds of Yttrium, Dysprosium, and HolmiumEarly reports about the ability of the 2-(dimethylaminomethy1)ferrocenyl group to form stable heterobimetallic organolanthanide(III) compounds have been confirmed by the synthesis of the organolanthanide(III) derivatives (C5H5)2Ln(FcN) [Ln = Y (II), Dy (III), Ho (IV)], C5H5Dy(FcN)2 · 2,5 THF (V) und C5H5Ln(FcN)Cl [Ln = Dy (VI), Ho (VII)] from the corresponding cyclopentadienyllanthanide(III) chlorides (C5H5)2LnCl or C5H5LnCl2 resp. and (FcN)Li (I). The products have been characterized by elemental analyses, IR-, 1H-NMR, 13C-NMR and UV/Vis spectra as well as mass spectra and the determination of their effective magnetic moments.

    Description / Table of Contents: Preparation and Characterization of Selenium Compounds with the 2,4,6-tris(trifluoromethyl)phenyl SubstituentReaction of 2,4,6-tris(trifluoromethyl)phenyl lithium and red selenium results in a product which by acidic hydrolysis yields bis[2,4,6-tris(trifluoromethyl)phenyl] diselenide 1. With diazomethane this compound reacts to form bis[2,4,6-tris(trifluoromethyl)phenylselenenyl] methane 2, with bis(triphenylphosphine)ethene platinum(0) the corresponding bis(triphenylphosphine)bis-[2,4,6-tris(trifluoromethyl)phenylselenenyl] platinum(II) 3 is formed. Chlorine and bromine cleave the selenium-selenium bond in 1 and 2,4,6-tris(trifluoromethyl)phenylselenenyl chloride 4 and -bromide 5 are formed.
