1-Alkyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane salts: a novel family of electrophilic fluorinating agents

Abstract
Members of a new series of solid, easily handled, storable, transportable, commercially viable, site-selective electrophilic fluorinating agents of the +N–F class (tradenamed Selectfluor reagents) have been synthesized via direct fluorination of monoquaternary salts of 1,4-diazabicyclo[2.2.2]octane.
