Efficient Synthesis of Isoquinoline Derivatives through Sequential Cyclization–Deoxygenation Reaction of 2-Alkynylbenzaldoximes

SynOpen, 2022
We describe a novel, simple, robust, and efficient cyclization/deoxygenation approach for the synthesis of functionalized isoquinoline derivatives. Over the course of continued studies on o-alkynylbenzaldoxime cyclization reactions, the formation of ...

A High-Performance Aqueous Zinc-Bromine Static Battery

iScience, 2020
Summary: The highly reversible zinc-bromine redox couple has been successfully applied in the zinc-bromine flow batteries; however, non-electroactive pump/pipe/reservoir parts and ion-selective membranes are essential to suppress the bromine diffusion ...

Signatures of the Bromine Atom and Open-Shell Spin-Coupling in the X-ray Spectrum of Bromobenzene Cation

, 2022
Table-top x-ray spectroscopy measurements at the carbon K-edge complemented by ab initio calculations are used to investigate the influence of the bromine atom on the carbon core-valence transitions in bromobenzene cation (BrBz+).

Bromine-terminated azobenzene liquid crystals

, 2018
A series of liquid crystals (LCs) of bromine-terminated azobenzene were synthesised and characterised. The LCs were composed of an azobenzene core, an alkyl chain and a flexible spacer with a bromine atom at a remote position. Mesomorphic properties were

The Effect of Bromine and Iodine on the Plant Growth, Phytochemical Composition and Antioxidant Capacity of Dandelion (Taraxacum officinale F.H. Wiggers Coll.) Plants

Molecules
Iodine is a crucial microelement for humans, and iodine deficiencies may be reduced through the consumption of iodine-enriched plants. The possible effects of exogenous bromine regarding plant growth, iodine biofortification efficiency, and the chemical ...

Electrophilic Activation of Molecular Bromine Mediated by I(III)

, 2023
In pursuit of a genuine Bromo-λ3-iodane, it has been found that the combination of Br2 and electron deficient λ3-iodanes can result in delivery of both bromine atoms from Br2 to a range of aryl substrates, some highly deactivated.
