Tin-containing Indane and Tetralin Derivatives [PDF]
Zeitschrift für Naturforschung B, 2009 The preparation of tin-containing indane and tetralin derivatives via two different reaction pathways is reported. The first route is the reaction of dichlorostannanes or bis(fluoroalkylsulfonyl)stannanes withα,α'-di(chloromagnesium)xylene. The second reaction is the direct coupling of chlorostannanes and α,α'-dichloroxylene which always yields a ...

Chemistry – An Asian Journal, EarlyView.3‐Dicyanomethylene thienothiophenes (CNTTs), a new series of electron acceptor units, were developed and incorporated into non‐fullerene acceptors (NFAs). The CNTT‐based NFAs exhibited favorable electronic structures and packing structures and thus enabled organic photovoltaic devices to achieve a power conversion efficiency of 10% when blended with ...

Journal of Basic Microbiology, EarlyView.ABSTRACT Rhizorhabdus wittichii RW1 is known for its ability to degrade polycyclic aromatic hydrocarbons, such as dibenzo‐p‐dioxin (DD) and dibenzofuran (DF). We hypothesized that the R. wittichii RW1 benzoate 1,2‐dioxygenase shares electron transfer components with the DD/DF angular dioxygenase (DxnA1A2), similar to many aromatic hydrocarbon degrading

Macromolecular Rapid Communications, EarlyView.The presented work demonstrates the importance of a comprehensive assessment of engineering plastics pyrolysis on the example of Polydicyclopentadiene. Analyses in µg‐, mg‐, and lab‐scale provide insight into mechanisms, yields, and products. An analytical and experimental toolset is showcased, by which the foundation for the assessment of pyrolysis as

Chiral Separations of Indan, Tetralin and Benzosuberan Derivatives by Capillary Electrophoresis [PDF]
, 1998 Several indan, tetralin and benzosuberan derivatives of diverse polarities were enantio-resolved by the use of sulfated β-cyclodextrins (CDs) or mixtures of sulfated β-CDs and γ-CD as chiral additives in capillary electrophoresis. Mixtures of sulfated 13-

The continuing significance of chiral agrochemicals
Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
