Abstract
A substitution reaction of O-, S-, or N-nucleophiles onto fluorinated isoxazolines via carbon–fluorine (C-F) bond cleavage was achieved. The C-F bond at the C5 position of fluorinated isoxazolines was dissociated by using SnCl4 for the generation of a carbocation intermediate in this reaction. Subsequently, various nucleophiles such as alcohols, thiols, and amines were introduced, enabling the conversion to CO, C-S, or CN bonds and the formation of a new quaternary carbon center.
期刊介绍：
The Journal of Fluorine Chemistry contains reviews, original papers and short communications. The journal covers all aspects of pure and applied research on the chemistry as well as on the applications of fluorine, and of compounds or materials where fluorine exercises significant effects. This can include all chemistry research areas (inorganic, organic, organometallic, macromolecular and physical chemistry) but also includes papers on biological/biochemical related aspects of Fluorine chemistry as well as medicinal, agrochemical and pharmacological research. The Journal of Fluorine Chemistry also publishes environmental and industrial papers dealing with aspects of Fluorine chemistry on energy and material sciences. Preparative and physico-chemical investigations as well as theoretical, structural and mechanistic aspects are covered. The Journal, however, does not accept work of purely routine nature.
For reviews and special issues on particular topics of fluorine chemistry or from selected symposia, please contact the Regional Editors for further details.
