Fire hazard is a constant risk in everyday life with the use of combustibles such as polymeric materials, wood, and fabrics, to name few. Halogenated compounds have been widely used efficient flame-retardants, often being applied coatings or impregnations. With growing environmental concerns regional bans on halogenated flame-retardant compounds, bio-based alternatives are garnering significant...

The use of halogens in the crystal engineering supramolecular porphyrin assemblies has been a topic strong interest over past decades. With this mind we have characterized series direct meso-halogenated porphyrins using single X-ray crystallography. This is accompanied by detailed conformational analysis all deposited CSD. In study used Hirshfeld fingerprint plots together with normal-coordinat...

In the combination of 5-fluorophenyl-1, 3, 7, 9-tetra methyl pyrido [2, 3, d, d, 5, 6 di pyrimidine -2, 4, 6, and 8 tetron, there are 4 rings, respectively, ring that is attached to the halogen ring A and, respectively, a ring The lower and the right to the left of the ring A are called C, B, and D. Calculations and studies show that the amount of aromatics in halogen-ring A in all cases has th...

THE effects of halogenated anesthetics on the myocardium have been studied extensively in vivo and in vitro in various animal species. In the past, investigators have focused their efforts on heart function, myocardial mechanics, and electrophysiology. During recent years, considerable knowledge has been obtained by new investigative methodologies, including molecular and cellular biology and a...

We observed distinct chemoselectivities for the gold-catalyzed transformation of cis-1-oxiranyl-1-alkynylcyclopropanes 1 into various halogenated products in the presence of suitable Au(III) catalysts and N-halosuccinimide (halo = chloro, bromo and iodo).

Two activated isostructural porous compounds, [Co(34pba)(44pba)] n ( 1d ) and [Zn(34pba)(44pba)] 2d (where 34pba is 3-(pyridin-4-yl)benzoate, 44pba 4-(pyridin-4-yl)benzoate, d indicates the phase) were used for adsorption of halogenated...
