This work covers homogeneous and biphasic catalysis in ionic liquids and water. The work presented herein is divided into two major parts: catalytic hydrogenation and catalytic hydroformylation. The first part also serves as an introduction to catalysis in ...
The efficiency of a two-step ozonation with regard to disinfection and oxidation of micropollutants; was assessed for a river-water treatment plant (Limmat River, Zurich, Switzerland). The assessment was based on laboratory experiments to estimate transien ...
FeZSM-5 with a wide range of Fe content (0.015–2.1 wt%) were studied in the benzene hydroxylation to phenol with nitrous oxide (C6H6:N2O = 1:5) at low temperatures (
Anaerobic biodegradation of hydrocarbons, using a variety of terminal electron acceptors (TEAs), is increasingly being reported both in laboratory studies and in the field. Of all the petroleum hydrocarbons, benzene is considered the most problematical due ...
The amino-amido-thiol AT (HS-(CH2)10-CO-NH-CH2-CH2-NH2)(HS-(CH2)10-CO-NH-CH2-CH2-NH2), adsorbed on Au(111), was studied by sum frequency generation (SFG) and IR reflection absorption spectroscopy in the CH2 stretching vibration region. The SFG and IR spect ...
Development of selective oxidation catalysts is a major concern of modern chemical industry. Among several systems, VTi-oxide based catalysts showed the most promising and versatile, able to catalyse key reactions like oxidation of o-xylene to phtalic anhy ...
The adsorption and ordering of the molecule terephthalic acid (TPA), 1,4-benzene-dicarboxylic acid C6H4-(COOH)(2), on the reconstructed Au(111) surface has been studied in situ in ultrahigh vacuum by scanning tunneling microscopy (STM) at room temperature. ...
The water soluble ruthenium-p-cymene complexes Ru(eta(6)-p-cymene)X-2 (X = Cl, Br, I or NCS), [Ru(eta(6)-p-cymene)X-2(pta)] (X=Cl, Br, I, or NCS; pta=1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane) and the tetraruthenium cluster [H4Ru4(eta(6)-p-benzene ...
Sulphur dioxide reacts with 1-oxydienes generating zwitterions which are quenched by enoxysilanes to form substituted silyl alkenylsulfinates. These intermediates are desilylated with Bu4NF and the resulting sulfinates react with MeI giving the correspondi ...
A two-step sequence involving an Ugi four-component reaction and an intramol. nucleophilic arom. substitution (SNAr) has been developed for the rapid access to biaryl-ether contg. macrocycles. For example, reacting heptanal with butylamine, (3-hydroxypheny ...
