Synthetic Study towards Strictamine: The Oxidative Coupling Approach

Qian Wang, Jieping Zhu, Weiwu Ren, Nicholas David Charles Tappin

A synthetic approach featuring a key intramolecular oxidative coupling of a dianion for the formation of the C7–C16 bond was exploited aiming at the synthesis of strictamine. Treatment of substituted tetrahydrocarboline with LHMDS at –78 °C followed by iod ...

Computational Quantum Chemical Studies on Radicals

Peter Rudolf Tentscher

Radicals play an important role in many areas of chemistry, such as atmospheric, aquatic, polymer, and biological, to name a few. Radicals are often highly reactive species which are short-lived and therefore harder to study by experimental techniques. In ...

Cross coupling of non-activated alkyl halides with alkynyl Grignard reagents catalyzed by a well-defined Ni pincer complex

Rosario Scopelliti, Xile Hu, Aurélien Godinat, Oleg Vechorkin

The nickel pincer complex 1 catalyzes the cross-coupling of the title compounds with remarkable substrate scope and functional group tolerance. A nickel/alkynyl species was isolated and shown to be catalytically competent. THF=tetrahydrofuran, O-TMEDA=bis[ ...

[(Methylcarbamothioyl)disulfanyl]methyl N-methylcarbamodithioate

Christine Neuhausen

The title compound, C5H10N2S5, was unintentionally obtained as the product of an attempted synthesis of a methyl-carbamodithioic acid using methylamine and carbon disulfide. In the molecule, two dithiocarbamate groups are bridged by a -CH2S- unit. The C-S- ...

Functional Nanostructures Based on Organometallic Half-Sandwich Complexes

Hexanuclear coordination cages of the formula [(C5Me4R)M(C7H3NO 4)]6 (M = Rh, Ir; R = Me, H) were obtained by stepwise reaction of [(C5Me4R)M(μ-Cl)Cl]2 with, first AgOAc and then pyridine-3,5-dicarboxylic acid. Crystallographic analyses show that the cages ...

In silico feasibility of novel biodegradation pathways for 1,2,4-trichlorobenzene

Vassily Hatzimanikatis, Stacey Deleria Finley

Background: Bioremediation offers a promising pollution treatment method in the reduction and elimination of man-made compounds in the environment. Computational tools to predict novel biodegradation pathways for pollutants allow one to explore the capabil ...

Electrical Properties and Photoconductivity of Stacked-Graphene Carbon Nanotubes

Klaus Kern, Marko Burghard, Eduardo Jian Hua Lee

Stacked-graphene carbon nanotubes (SG-CNTs) obtained via pyrolysis of columnar superstructures of polycyclic aromatic hydrocarbons are studied by electrical transport measurements and scanning photocurrent microscopy. The charge transport in individual SG- ...

trans-Decahydronaphthalene (decalin) from powder diffraction data

Philip Pattison

The title compound, C10H18, a decalin stereoisomer, crystallizes with Z' = 0.5 in the space group P21/n. The trans-decalin molecule is located on an inversion centre with both rings in a chair conformation, making for a quasi-flat overall shape. Despite th ...

Search for new anti-cancer heterocyclic compounds

Claudia Bello

Tumors consist of cells whose growth and morphological characteristics are markedly different from those of normal cells. Observation of human and animal models argue that tumor development proceeds via a process formally analogous to Darwinian evolution, ...
