The reaction of aryl bromides with allylic alcohols catalysed by a Pd-benzothiazole carbene complex, in tetrabutylammonium bromide as solvent, leads principally to β-arylated carbonyl compounds. ( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)DOI...
En route to the first synthesis of the two long-known naturally occurring coumarins, several broadly employed coupling protocols were examined for the given substrates without success. In the end, the desired products were obtained by performing the reaction in xylene at 160°C in the presence of...
The reaction intermediates in the synthesis of 2,2′-bis(pyridyl) diselenide (2,2′-Py2Se2) have been determined. The reaction of Na2Se2 with 2-BrC5H4N (2-... Jrg Laube,Stefan Jger,Carsten Thne - 《European Journal of Inorganic Chemistry》 被引量: 48发表: 2001年 Synthesis and charact...
The cover picture provided by Andreas Pfaltz,depicts a schematic representation of the catalytic cycle of the Ir-catalyzed asymmetric hydrogenation of non-functionalized alkenes along with a space-filling model of one of the outstanding catalysts for this reaction.

aIn this work, the synthesis and characterization of the thiosemicarbazide-grafted MWCNTs for selective solid-phase extraction of Cd(II), Cu(II), Pb(II) using an amidation reaction from acyl chloride have been present. The result showed the MWCNTs-TB could be employed as SPE material, the MWC...
Although little is known about the mechanism of this iridiumcatalyzed carbonyl group hydrogenation reaction, a non‐classical metalligand bifunctional mechanism deserves to be recommended to interpret the high efficiency of this catalyst. With the help of KO‐ t ‐Bu and under an H 2 atmosphere, ...
Kinetic study of the reaction betweentrans-aquanitridotetra-cyanorhenate(V) and different cyanide species The kinetics of the reaction between [ReN(H 2 O) (CN) 4 ] 2− and cyanide has been studied in the ca. pH 8–14 range. The aqua ligand in the [ReN(H 2 O)(... LJ Damoense...
