The temperature of spin-crossover in [Fe(3-bpp)(2)][BF(4)](2) (3-bpp = 2,6-di{pyrazol-3-yl}pyridine) tends to increase in associating solvents. In particular, T(½) shifts to 60-70 K higher temperature in water compared to organic solvents.

A self-assembled M(2)L(4) palladium-pyridyl cluster with a "paddle-wheel" structure shows binding affinity in competitive organic solvents for neutral organic guests that possess both the correct size and electrostatic complementarity.

We report a green and convenient protocol to prepare 4,7,12,15-tetrachloro[2.2]paracyclophane, the precursor of parylene D, from 2,5-dichloro-p-xylene. In the first bromination step, with H2O2-HBr as a bromide source, this procedure becomes organic-waste-free and organic-solvent-free and can appropriately replace the existing bromination methods. The Winberg elimination-dimerization step, using...

Various effects of exposure to volatile organic compounds (VOC) have recently become an important issue because of their widespread use in industry. The aim of this study was to determine the effect of volatile organic solvents commonly used in textile paint industry on free radical levels and the antioxidant enzyme system in textile workers. The study included twenty exposed workers and twenty...
