Enforced Electronic?Donor?Acceptor Complex Formation in Water for Photochemical Cross?Coupling
نویسندگان
چکیده
The amino alcohol meglumine solubilizes organic compounds in water and enforces the formation of electron donor acceptor (EDA) complexes haloarenes with indoles, anilines, anisoles or thiols, which are not observed solvents. UV-A photoinduced transfer within EDA induces mesolytic cleavage halide ion radical recombination arenes leading, after rearomatization proton loss to C?C C?S coupling products. Depending on substitution pattern selective unique cross-couplings observed. UV NMR measurements reveal importance assembly for reaction. Enforced aggregate allows new activation modes photochemical synthesis.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Efficient photochemical water oxidation by a dinuclear molecular ruthenium complex.
Herein is described the preparation of a dinuclear molecular Ru catalyst for H2O oxidation. The prepared catalyst mediates the photochemical oxidation of H2O with an efficiency comparable to state-of-the-art catalysts.
متن کاملPhotochemical formation of intricarene.
Sunlight is the ultimate driver of biosynthesis but photochemical steps late in biosynthetic pathways are very rare. They appear to play a role in the formation of certain furanocembranoids isolated from Caribbean corals. One of these compounds, intricarene, has been suspected to arise from an intramolecular 1,3-dipolar cycloaddition involving an oxidopyrylium. Here we show, by a combination of...
متن کاملSpectrophotometric Methods for Determination of Sunitinib in Pharmaceutical Dosage Forms Based on Ion-pair Complex Formation
Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...
