1,1?,2,2?-Tetralithioferrocene and 1,1?,2,2?,3,3?-Hexalithioferrocene: Useful Additions to Ferrocene Precursor Compounds
نویسندگان
چکیده
The direct synthesis of 1,1?,2,2?-tetralithioferrocene from 1,1?,2,2?-tetrabromoferrocene is reported. In addition, the related 1,1?,2,2?,3,3?-hexalithioferrocene also described, prepared directly 1,1?,2,2?,3,3?-hexabromoferrocene. These lithioferrocenes may be isolated as orange red (tetralithio) and (hexalithio) powders, respectively. When these are in situ reacted with chlorotrimethylsilane, corresponding 1,1?,2,2?-tetrakis(trimethylsilyl)ferrocene 1,1?,2,2?,3,3?? -hexakis(trimethylsilyl)ferrocene obtained crimson crystalline solids, single-crystal structures (11) 1,1?,2,2?,3,3?-hexakis(trimethylsilyl)ferrocene (12) have been determined described.

precursor for radiolabeled compounds useful in Positron Emission Tomography
A variety of compounds radiolabeled with Tc(140 keV γ T1/2=6 hours) are widely used in nuclear medicine imaging. These compounds can also be radiolabeled using positron-emitting precursor TcO4 (T1/2=53 minutes) and used with Positron Emission Tomography (PET) to measure tissue concentrations in μCi/cm, and produce kinetic data useful to understand the mechanism of drug action. This work-in-prog...
متن کاملCatalytic C,C-bond forming additions to unsaturated fatty compounds
A large number of novel fatty compounds have been synthesized by catalytic C,C-bond forming addition reactions to the C,Cdouble bond of unsaturated fatty compounds. Radical reactions such as the solvent-free addition of -halocarboxylic acid esters initiated by electron transfer, e.g., from copper to give fat-derived -lactones are described as well as Lewis acid–induced electrophilic addition re...
متن کاملFerrocene Compounds. XII*. Reactions of Ferrocene- carbaldehyde with Benzanilides and n-Butyllithium
The reactions of ferrocenecarbaldehyde with benzanilides, and n-butyllithium, depending on the benzanilide used, gave mixtures of 1-hydroxypentylferrocene, 1-phenoxypentylferrocene, pentylferrocene, hydroxymethylferrocene, bis(ferrocenylmetyl) ether and ferrocene. The mixtures obtained have been separated into pure components by chromatographic methods and their structures have been assigned by...
متن کاملAnion-Tunable Properties and Electrochemical Performance of Functionalized Ferrocene Compounds
We report a series of ionically modified ferrocene compounds for hybrid lithium-organic non-aqueous redox flow batteries, based on the ferrocene/ferrocenium redox couple as the active catholyte material. Tetraalkylammonium ionic moieties were incorporated into the ferrocene structure, in order to enhance the solubility of the otherwise relatively insoluble ferrocene. The effect of various count...
