The ring skeleton of the title compound, C(14)H(4)Cl(2)N(2)O(6), is close to planar (r.m.s. deviation of the carbon atoms 0.091 Å); the nitro goups are twisted with respect to the mean plane of the ring system by 70.8 (1) and 86.7 (2)°. The crystal studied was found to be a merohedral twin, with a domain ratio of 0.61 (8):0.39 (8).

In the title compound, C(25)H(16)N(4), the fused ring system is essentially planar [maximum deviation = 0.1012 (15) Å]. The imidazole ring makes dihedral angles of 77.41 (8) and 56.26 (8)° with the phenyl rings attached to nitro-gen and carbon, respectively. The dihedral angle between the two phenyl rings is 65.50 (8)°. Weak C-H⋯π inter-actions are found in the crystal structure.

Benzyl bromides and related molecules are among the most common substrates in organic synthesis. They are typically used as electrophiles in nucleophilic substitution reactions. These molecules can also be activated via single-electron-transfer (SET) process for radical reactions. Representative recent progress includes α-carbon benzylation of ketones and aldehydes via photoredox catalysis. Her...

As an electrophile, bromonitromethane was used as a versatile reagent in the synthesis of aminothiophenes and their derivatives as well as in the reaction with nucleophiles such as thiolates, sulphides, thiourea, thiocyanate, iodide and phosphorus based species [1]. Bromonitromethane contains only one carbon atom, therefore it is relevant to C-1 chemistry [2]. In chemical synthesis, it has two ...

This study aims to investigate the anaerobic degradation kinetics of reactive dye, C.I. Reactive Red 141 (Evercion Red H-E7B) by partially granulated anaerobic mixed culture using three carbon sources, namely modified starch (MS), polyvinyl alcohol (PVA) and acrylic size (AS) during batch incubation. There is a first-order kinetics reaction in the decolorization processes using MS and PVA as ca...

Glossary Carbon sequestration: capture and secure storage of carbon that would otherwise be emitted to or remain in the atmosphere. Carbon sources: for this chapter, we are concerned with large stationary sources of CO2, e.g. fossil fueled power plants, cement manufacturing, ammonia production, iron and non-ferrous metal smelters, industrial boilers, refineries, natural gas wells. Carbon captur...

Synthesis of the exopolysaccharide-based bioflocculant Rhizobium radiobacter SZ4S7S14 was researched and medium optimized for enhanced production of bioflocculant. D-Mannose and yeast extract were found to be best carbon and nitrogen sources for maximal yield of bioflocculant. The bioflocculant samples obtained in different media with different carbon and nitrogen sources were further analyzed ...

Arsenic from two sources--arsanilic acid and 3-nitro-4-hydroxyphenylarsonic acid (3-nitro)--was fed to mature wethers and lactating dairy cows, and the uptake and depletion of arsenic in tissues and milk were determined. In experiments with sheep, arsenic concentration in liver, kidney and blood increased as the level of arsenic from arsanilic acid and 3-nitro was increased in feed. Muscle arse...
