Photoredox catalysis has become a powerful tool for chemists. However, the reliance on expensive Ir and Ru based photoredox catalysts (PC) motivates research for more sustainable options. Copper complexes based on favorable photophysical properties, high a ...
The objective of this study was to analyze the behavior of a new material, silver-doped polymeric cloth (Ag-cloth), in the removal of bromide and iodide from waters. Silver is immobilized on the cloth, guaranteeing selective adsorption of the halide ions a ...
Reaction of alkenes with N-bromosuccinimide and Et3N.3HF produces vic-bromofluoroalkanes in high yields. As long as the addn. to the C:C bond is sterically unhindered, Br and F get attached with very high regioselectivity, the latter occupying the more sub ...
The reaction of isocyanomethylenetriphenylphosphorane, generated in situ from the corresponding phosphonium salt, with a diverse set of aldehydes afforded vinyl isocyanides in good to high yields. Excellent E-selectivity was observed for aliphatic aldehyde ...
This thesis deals with a laboratory study of heterogeneous reactions involving bromine and chlorine containing reservoir species on alkali salt substrates which are relevant to the marine boundary layer, and on ice substrates which are relevant to the lowe ...
A series of homologous bis-cyclometalated iridium(III) complexes Ir(2,4-di-X-phenyl-pyridine)2(picolinate) (X = H, F, Cl, Br) HIrPic, FIrPic, ClIrPic, and BrIrPic has been synthesized and characterized by NMR, X-ray crystallography, UV–vis absorption and e ...
Upon treatment of 1-bromo-2-(trifluoromethoxy)benzene with lithium diisopropylamide (LDA) at -100 DegC, 3-bromo-2-(trifluoromethoxy)phenyllithium is generated. It can be trapped as such, but isomerizes to afford 2-bromo-6-(trifluoromethoxy)phenyllithium wh ...
The alcoholate-promoted dehydrohalogenation of 5-nonyl fluoride and cyclododecyl fluoride, typical straight-chain and, resp., medium-size cyclic substrates, leads to cis- and trans-alkenes in an approx. ratio of 1:3. With bulky bases such as lithium diisop ...
The objective of this study was to remove halides from waters by silver nanoparticles (AgNPs) and hydrogen peroxide (H2O2). The experimental parameters were optimized and the mechanism involved was also determined. The AgNP/H2O2 process proved efficacious ...
Inspired by Nature several groups have developed structural and functional iron complexes mimicking the active site of the iron-hydrogenases, which show high reactivity in the H2 cleavage. Usually pendant bases have been incorporated onto families of Fe co ...
