TLDR
In this article, the polarographic parameters obtained have been correlated with the p K a values of RH and the best correlation is obtained for a plot of the half-wave reduction potentials E 1 2 of π-C 5 H 5 Fe(CO) 2 -σ-R and the p k a a values for ferrocene, cyclopentadienylmanganese and rhenium tricarbonyls as CH acids.About:

1,1-Dimethylsilacyclobutane-Mediated Living Anionic Block Copolymerization of [1]Dimethylsilaferrocenophane and Methyl Methacrylate
TL;DR: In this article, an efficient synthesis of diblock copolymers from femoral carbon carbonenophane (FS) and methyl methacrylate (MMA) is described, where a combination of an accelerator (DMSB) and an end-capping agent (DPE) is shown to suppress side reactions which otherwise lead to significant quantities of PFS homopolymers.

TL;DR: In this paper, two methods were compared to convert ferrocene into N,N-diisopropylferrocenecarboxamide, N,D-diethylferrichenecaroxamides, and (4-morpholinocarbonyl)ferrocene, namely, deprotometalation followed by trapping using dialkyl carbamoyl chlorides and amide formation from the intermediate carboxylic acid.

Influence of the Axial Alkyl Ligand on the Reduction Potential of Alkylcob(III)alamins and Alkylcob(III)yrinates
TL;DR: In this paper, the irreversible reduction potential of 26 alkylcob(III)alamin (RCblIII1a-z) and 26 RCblIII (RCoIII + e−⇆R⋅ + CoI) was measured in situ by single-scan voltammetry of hydroxocob( IIIalamin hydrochloride (vitamin B12b-HCl).

TL;DR: The transient intermediate η2-cyclopropene/bicyclobutane niobium complex [TpMe2Nb(η 2-c-C3H4)(MeCCMe)] as discussed by the authors, generated by an intramolecular β-H abstraction of methane from the methyl cyclopropyl complex, is able to cleave the CH bond of a variety of unsaturated hydrocarbons in a selective manner to give the corresponding hydrocarbyl complexes.
