The preparation and properties of diorganoselenium difluorides
The synthesis of a number of alkyl- and aryldiorganoselenium difluorides is reported from the reaction of silver (II) fluoride with diorganoselenides. Diorganoselenium difluorides are liquids or low-melting solids which are monomers in benzene solution. Infrared and 19F and 1H nmr data are presented and discussed with regard to bonding and fluorine exchange in these compounds.
Hexafluoropropene oxide - a fluorinating reagent for the formation of element-fluorine bonds
Hexafluoropropene oxide (HFPO) is shown to be a good reagent for the nucleophilic formation of the element-fluorine bond in organoelement compounds. Fluorides of Bi, Sb, Se, Te and I were prepared from appropriate oxygen compounds.
