Paramagnetic Solid-State NMR Study of Solid Solutions of Cobaltocene with Ferrocene and Nickelocene

Magnetochemistry
The metallocenes ferrocene (Cp2Fe, 1), nickelocene (Cp2Ni, 2), and cobaltocene (Cp2Co, 3) crystallize in the same space group (P21/a) and they have the same shape and similar size.

Synthesis, Structure and Electrical Resistivity of Carbon Nanotubes Synthesized over Group VIII Metallocenes

Nanomaterials, 2020
The paper reports the synthesis of carbon nanotubes from ethanol over group VIII (Fe, Co, Ni) catalysts derived from corresponding metallocenes. Several unexpected cooperative effects are reported, which are never observed in the case of individual ...

Self-contained Kondo effect in single molecules

, 2005
Kondo coupling of f and conduction electrons is a common feature of f-electron intermetallics. Similar effects should occur in carbon ring systems(metallocenes).

Design and Synthesis of Hydroxyferroquine Derivatives with Antimalarial and Antiviral Activities [PDF]

, 2006
Three ferroquine (FQ) derivatives, closely mimicking the antimalarial drug hydroxychloroquine (HCQ), have been prepared. Whereas these organometallic compounds provide the expected reduced cytotoxic effects compared to FQ, they inhibit in vitro growth of

A base-free synthetic route to anti-bimetallic lanthanide pentalene complexes [PDF]

, 2017
We report the synthesis and structural characterisation of three homobimetallic complexes featuring divalent lanthanide metals (Ln = Yb, Eu and Sm) bridged by the silylated pentalene ligand [1,4-{SiiPr3}2C8H4]2− (= Pn†).

Harnessing Toluene Solvent as a Reactant: Regioselective Benzyl Radical Addition to Multi‐π 1,5‐Enynes in a Copper‐Catalyzed Cascade to Indenes

Chemistry – A European Journal, EarlyView.
A copper‐catalyzed three‐component radical cascade of 1,5‐enynes with toluene and benzoic acids enables regioselective benzyl radical addition to multi‐Π systems, efficiently delivering polysubstituted indenes from an abundant solvent feedstock. ABSTRACT C─H activation of toluene generates a benzyl radical that undergoes C─C coupling, converting an ...

Advantages of Group 4 Metallocene Bis(trimethylsilyl)acetylene Complexes as Metallocene Sources Towards Other Synthetically used Systems

ChemistryOpen, 2019
Active species for synthetic and catalytic applications are formed from well defined complexes or mixtures of compounds. For group 4 metallocenes, three pathways for the formation of the reactive complex fragment [Cp′2M] are known: (i) reductive mixtures

Synthesis and Characterization of Cerium(IV) Metallocenes

Inorganics, 2015
By applying a salt metathesis approach between Ce(OtBu3)2(NO3)2(THF)2 and the potassium salts of mono- and ditrimethylsilyl substituted cyclopentadienes, we were able to isolate two new Ce(IV) metallocenes, including to the best of our knowledge, the ...

A novel n‐type dimer dopant for semiconducting polymers

Polymer International, EarlyView.
A novel molecular n‐type dopant (1) with superior capacity to dope conjugated polymers is introduced. After charge transfer the product (2) remains in the polymer. Abstract Efficient and stable doping of organic semiconductors is crucial for adjusting their electrical properties.
