European Journal of Inorganic Chemistry, EarlyView.The lithium enediamide complex 2 with intrinsically inverted C–N bond polarity combines strong basicity with unusual reactivity: deprotonation of malonates enables C–C bond formation without electron transfer. Depending on malonate substitution, electrophilic substitution or addition occurs at the enediamide CC bond.

Polarization and Spectral Shift of Benzophenone in Supercritical Water [PDF]
, 2009 Monte Carlo simulation and quantum mechanics calculations based on the INDO/CIS and TD-DFT methods were utilized to study the solvatochromic shift of benzophenone when changing the environment from normal water to supercritical (P = 340.2 atm and T = 673

European Journal of Inorganic Chemistry, EarlyView.Upon reduction of 1,4‐diaza‐1,3‐diene 1 to the dilithium enediamide 2, the polarity of the C = N bonds is reversed ‐ a classic case of umpolung. This behavior is particularly evident in reactions of the dianion 2 with carbonyl compounds and also explains why 1,4‐diaza‐1,3‐diene ligands do not always act merely as spectator ligands. 1,4‐Diaza‐1,3‐dienes

European Journal of Organic Chemistry, EarlyView.Molecules with unpaired electrons, also known as open‐shell systems, are key intermediates in several light‐mediated or metal‐catalyzed transformations in organic chemistry. However, modeling this chemistry by density functional theory calculations is challenging.

Photochemistry of benzophenone on Ti-MCM-41 surfaces [PDF]
, 2013 Diffuse reflectance and chromatography techniques were used to study three Ti-MCM-41 solid powders, containing 1%, 2.5% and 8% of Ti, and to investigate the photochemistry of benzophenone adsorbed on their surfaces. The observed ground state absorption,

In Utero Exposure to Benzophenone-2 Causes Hypospadias Through an Estrogen Receptor Dependent Mechanism [PDF]
, 2007 Purpose: Additives such as benzophenone-2 are commonly used in cosmetic products and food container plastics to filter out ultraviolet light. In pregnant women exposure may result in transplacental transfer of benzophenone-2 to fetuses. Benzophenone-2 is

Photochemistry of benzophenone adsorbed on MCM-41 surface [PDF]
, 2013 The photochemistry of benzophenone adsorbed on a channel-type solid support MCM-41 was studied by the use of diffuse reflectance and chromatographic techniques. For comparison purposes parallel studies were also conducted on silicalite and H-ZSM-5. The
