Structures and Reactivities of Organolithium Compounds

The characteristic species present in organolithium compounds under various conditions are reviewed. The effects of environment on the kinetics and energetics of exchange reactions are discussed. A summary is given of various pathways by which organolithium compounds might react. Kinetic and spectroscopic evidence for these processes under various conditions are reviewed. A discussion is presen...

Computational study of electronic, spectroscopic, and chemical properties of (CdO)n (n=1-7) nanoclusters as a transparent conducting oxide

An ab initio study has been performed for the electronic, spectroscopic, and chemical properties of the most stable configuration of the (CdO)n nanoclusters by employing B3LYP-DFT/LanL2DZ method. Different isomers were optimized to obtain structural stability and numerous chemical parameters such as dipole moment, ionization potential, etc. We report here the vibrational frequencies of the most...

Nitrogen starvation promotes biodegradation of N-heterocyclic compounds in soil

Mineralization studies were performed to examine the impact of N deprivation on microbial utilization of the N-heterocyclic herbicides, atrazine and cloransulam-methyl (C-M). Soil depleted by 130 years of cropping to Zea mays without fertilization was contrasted to soil from the same site regularly receiving fertilizers. Long-term N deprivation promoted rapid degradation of atrazine and the C-M...

Glutathione peroxidase-like activity of simple selenium compounds. Peroxides and the heterocyclic N-oxide resazurin acting as O-atom donors.

Selenite and selenocystamine [(CyaSe)2] efficiently activate the decomposition of H2O2 by GSH and by other thiols, as demonstrated using a leuco crystal violet POD-based H2O2 assay which is applicable (unlike other assays) also in presence of thiols. The GPx-like activities were estimated to be 3.6 and 2.7 mumol H2O2/min per mumol SeO3(2-) and (CyaSe)2, respectively. Both selenium compounds als...
