OBJECTIVES The purpose of this study was to measure the concentration of volatile organic compound (VOC)s originated from the chemicals used and/or derived from the original parental chemicals in the photolithography processes of semiconductor manufacturing factories. METHODS A total of four photolithography processes in 4 Fabs at three different semiconductor manufacturing factories in Korea...

Organocopper reagents constitute a key class of organometallic reagents, with numerous applications in organic synthesis [1]. Their high reactivities and chemoselectivities have made them unique intermediates. Most reports use organocopper reagents of type 1 or 2, which are prepared from organolithiums. This transmetalation procedure confers optimal reactivity, but in many cases it permits only...

It is now well-known that (2)H solid-state NMR techniques can bring a better understanding of the interaction of deuterium with metal atoms in organometallic mononuclear complexes, clusters or nanoparticles. In that context, we have recently obtained experimental quadrupolar coupling constants and asymmetry parameters characteristic of deuterium atoms involved in various bonding situations in r...

The toxicity of organometallic compounds may arise from the level of their adsorption to the lipid phase of biological membranes. It is also assumed that the toxicity of some organometallic compounds may relates to their free-radical properties with respect to lipids, proteins and DNA, under certain conditions. It is very probable that the relatively long life-span in the animal body of such ra...

The discovery of novel drugs against animal parasites is in high demand due to drug-resistance problems encountered around the world. Herein, the synthesis and characterization of 27 organic and organometallic derivatives of the recently launched nematocidal drug monepantel (Zolvix® ) are described. The compounds were isolated as racemates and were characterized by 1 H, 13 C, and 19 F NMR spect...

Metallocenes are well-established compounds in organometallic chemistry, which can exhibit either coplanar or bent structures according to the nature of metal center (M) and cyclopentadienyl ligands (Cp). Herein,...
