Laser-ablated U atoms react with CO in excess argon to produce CUO, which gives rise to 852.5 and 804.3 cm-1 infrared absorptions for the triplet state CUO(Ar)n complex in solid argon at 7 K. Relativistic density functional calculations show that the

During the past decade a number of HRgY molecules (H ) hydrogen; Rg ) Ar, Kr, Xe; Y ) an electronegative fragment) have been characterized experimentally in rare-gas solids and computationally by using ab initio methods.1,2 These species are formed f

When water is heated and pressurized above the critical point, it becomes a suitable solvent to employ organic capping ligands to control and stabilize the synthesis of nanocrystals. Without alkanethiol ligands, Cu(NO(3))(2) hydrolyzes to form polydi

The vapor of (chlorocarbonyl)sulfenyl bromide, ClC(O)SBr, was isolated in solid Ar, Kr, N(2), and Ar doped with 5% CO at 15 K, and the matrix was subsequently irradiated with broad-band UV--visible light (200or = lambdaor = 800 nm), the changes being

We here report the first direct evidence addressing the possible involvement of Mo in substrate interactions during catalytic turnover. When the alpha-70(Ile) MoFe protein is freeze-trapped during H(+) reduction under Ar, the majority of the resting

The new terphenyl pincer precursor 3,3‘ ‘-di-tert-butyl-1,1‘:3‘,1‘ ‘-terphenyl-2,2‘ ‘-diol (1) is examined for its ability to support early transition metals as a trianionic ligand. Metalation proceeds smoothly at −35 °C with Mo(NM

Copper is a key metal ion both in environment monitoring and in biology, and exposure to high concentration of copper can cause adverse health effects. Although significant progresses have been made in designing fluorescent sensors for diamagnetic me

We report the formation of high-precision catalysts using encapsulated rhodium complexes. In the current example, the encapsulated rhodium catalyst shows unprecedented high selectivity in the rhodium-catalyzed hydroformylation of internal alkenes, fo
