Product Name:Selectfluor Reagent
English Name:1-ChloroMethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate)
CAS No.:140681-55-6
Aliases:Selectfluor, 1-(Chloromethyl)-4-fluoro-1,4-diazabicyclo[2.2.2]octane bis(tetrafluoroborate)
Molecular Formula:C7H14B2ClF9N2
Physical Properties:White crystalline powder; melting point approximately 290°C (decomposition). Readily soluble in water, acetonitrile, and alcohols; slightly soluble in dichloromethane; insoluble in diethyl ether, petroleum ether, and other non-polar solvents. Good thermal stability; acts as a mild and selective electrophilic fluorinating reagent.
Uses:Widely used as an electrophilic fluorinating reagent for the selective introduction of fluorine atoms into aromatic rings, alkenes, carbonyl compounds, and other organic molecules. It is extensively applied in the fluorination and modification of pharmaceuticals, agrochemicals, and fine chemical intermediates.
