Cymantrene–Triazole "Click" Products: Structural Characterization and Electrochemical Properties [PDF]

, 2014
We report the first known examples of triazole-derivatized cymantrene complexes (η5-[4-substituted triazol-1-yl]cyclopentadienyl)tricarbonylmanganese(I), obtained via a “click” chemical synthesis, bearing a phenyl, 3-aminophenyl, or 4-aminophenyl moiety ...

Paired electrolysis-enabled nickel-catalyzed enantioselective reductive cross-coupling between α-chloroesters and aryl bromides

Nature Communications, 2022
Precise matching of reaction rate and electric potential of electrodes in paired electrolysis is challenging. Here, the authors develop paired-electrolysis-enabled nickel-catalyzed enantioselective reductive cross-coupling of α-chloroesters and aryl ...

Hexagonal MASnI$_3$ exhibiting strong absorption of ultraviolet photons

, 2019
MASnI$_3$, an organometallic halide, has great potential in the field of lead-free perovskite solar cells. Ultraviolet photons have been shown to generate deep trapping electronic defects in mesoporous TiO$_2$-based perovskite, affecting its performance ...

New Discoveries in the Realm of Metal–Metal Multiple Bonds:[η5-(C5Me5)Co2], the First Organometallic Multiple-Bond Complex without Bridging Ligands [PDF]

, 1991
Double bond, yes or no? That is the poignant question in the case of the complex [Cp*CoCoCp*] prepared by J.J. Schneider et al. The Co-Co distance and the number of electrons suggest a double bond, while the H-1-NMR spectrum and the poor reactivity ...

Tamoxifen-like metallocifens target thioredoxin system determining mitochondrial impairment leading to apoptosis in Jurkat cells [PDF]

, 2017
Tamoxifen-like metallocifens (TLMs) of the group-8 metals (Fe, Ru, and Os) show strong anti-proliferative activity on cancer cell lines resistant to apoptosis, owing to their unique redox properties. In contrast, the thioredoxin system, which is involved

Organocatalytic synthetic route to esters and their application in hydrosilylation process

Scientific Reports
A facile esterification of α,β-unsaturated aldehydes with alcohols has been developed for the synthesis of esters by using bulky N-heterocyclic (NHC) carbene as a metal-free and eco-friendly organocatalyst.

Electronic correlations in organometallic complexes

, 2011
We investigate an effective model for organometallic complexes (with potential uses in optoelectronic devices) via both exact diagonalisation and the configuration interaction singles (CIS) approximation.
