This book represents first non-edited book on the subject of metal catalysed reactions in ionic liquids and covers the literature from its origins until early 2005. Following a general introduction to the field of biphasic/mutliphasic catalysis, the synthe ...
A series of relatively low-cost ionic liquids, based on the N-butyronitrile pyridinium cation C(3)CNpy, designed to improve catalyst retention, have been prepared and evaluated in Suzuki and Stille coupling reactions. Depending on the nature of the an ...
New conditions have been found for the desulfitative Mizoroki-Heck arylation and trifluoromethylation of mono- and disubustituted olefins with arenesulfonyl and trifluoromethanesulfonyl chlorides. Thus (E)1,2-disubstituted alkenes with high stereoselectivi ...
Ionic liquids are excellent solvents for conducting biphasic hydrogenation reactions offering many advantages over both related homogeneous processes and biphasic reactions in other alternative solvents. The relevant physicochemical properties of ionic liq ...
The first aza-C-disaccharide (D-azaMan-beta-CHz-(1 -> 6)-D-Man-alpha-OMe) that mimicks alpha-D-Manp-(1 -> 6)-alpha-D-ManOMe was made in 1994 by Johnson and coworkers. Several synthetic approaches to these disaccharide mimetics have been proposed. These are ...
This thesis reports on the investigations performed on electrochemical functionalization and photoelectronic transport properties of individual single-wall carbon nanotubes (SWCNTs). The first part of the thesis is concerned with the controlled modificatio ...
The reaction of [RuCl3(AsPh3)(2)(MeOH)] with the dimeric complexes (cod)RhCl, (ppy)RhCl (ppy = cyclometalated 2-phenylpyridine), (cymene)RuCl2 and CP*MCl2 (M = Rh, Ir) has been investigated. The structure of the resulting products was s ...
In the first part, we described the synthesis of C-(1'→1) and C-(1'→4) disaccharide precursors, which are readily obtained via the carbonylative Stille coupling of glucal and isolevoglucosenone derivatives. Tin glycals and triflates, derived from isolevogl ...
Maintaining a fuel cell system in correct operating conditions when subjected to fast load changes requires good system control. In order to design such a controller, a simple PEFC system model describing all the important system dynamics and cross couplin ...
Arene-, arylmethane, and alk-2-ene-1-sulfonyl chlorides undergo Suzuki-Miyaura cross-coupling with arene-, heteroarene-, and alkeneboronic acids in THF at reflux. The reactivity order is Arl > ArSO2Cl > ArBr much greater than ArCl. ...
