Novel chiral phosphonium ionic liquids as solvents and catalysts for cycloadditions. Investigation of the Diels-Alder reaction of a series of dienes and dienophiles in novel chiral phosphonium ionic liquids.
The use of ionic liquids (ILs) as both reagents and solvents is widely recognised. ILs offer a number of advantages compared to regular molecular solvents. These advantages include: chemical and thermal stability, no measurable vapour pressure, no or lower toxicity, non-flammability, catalytic …

The sol-gel polymerization of octamethoxysilsesquioxane
In order to understand the effect of various solvents and catalysts on the sol-gel polymerization of [SigOi2](OCHg)g, the polymerization was followed by 29Si NMR spectroscopy, which indicated that the cubic structure of [SigOi2](OCH3)g was retained under initial polymerization conditions. …

Zur Oligomerisierung von 1-Decen mit ionischen Flüssigkeiten
… (PAO), are used as base oils for lubricants and stand out due to a high stability combined with extraordinary greasing properties. Ionic liquids have properties that are variable in a wide range (polarity, acidity) and are employed both as solvents and catalysts. They are very well suited for …

Green Photochemistry: The synthesis of fine chemicals with sunlight
… optimised procedure to a library of 1-naphthols and the investigation of photooxygenation reactions in alternative media. The dye-sensitised photooxygenation of 1,5-dihydroxynaphthalene to form juglone ([4+2]- cycloaddition reaction) was used as a model reaction to develop an entirely ‘green’ …
