3-Cyanoanilinium bromide [PDF]

open access: goldActa Crystallographica Section E Structure Reports Online, 2009
In the cation of the title compound, C(7)H(7)N(2) (+)·Br(-), all non-H atoms are essentially coplanar [r.m.s. deviation = 0.010 (5) Å]. The compound is isomorphous with the chloride analogue. In the crystal, the cations and anions are connected by N-H⋯Br hydrogen bonds.

The Role of Sulphate and Phosphate Ions in the Recovery of Benzoic Acid Self-Enhanced Ozonation in Water Containing Bromides

open access: yesMolecules, 2021
The ozonation of aromatic compounds in low-pH water is ineffective. In an acidic environment, the decomposition of ozone into hydroxyl radicals is limited and insufficient for the degradation of organic pollutants.

Catalysis by alkali and alkaline-earth metal ions in nucleophilic attack of methoxide ion on crown ethers bearing an intra-annular acetoxy group [PDF]

open access: yes, 1989
Rates of reaction of methoxide ion with crown ethers bearing an intra-annular acetoxy group are markedly enhanced by alkali and alkaline-earth metal bromides as a result of much stronger interactions of the metal ions with transition states than with ...

Tiotropium bromide [PDF]

open access: yesInternational Journal of COPD, 2006
Therapy with bronchodilators forms the pharmacologic foundation of the treatment of patients with COPD. Bronchodilators can significantly lessen dyspnea, increase airflow, improve quality of life, and enhance exercise performance. While bronchodilators decrease airway resistance and lessen dynamic hyperinflation in patients with COPD, they have not ...

Palladium-catalyzed acetylation of arenes. [PDF]

open access: yes, 2014
A simple method for the preparation of aryl methyl ketones is reported. The transformation involves the Pd-catalyzed coupling of an acyl anion equivalent, acetyltrimethylsilane, with aryl bromides to afford the corresponding acetylated arenes in ...
