Abstract
The present invention relates to novel N,N'-difluorinated diazabicycloalkane derivatives which are useful as electrophilic fluorinating agents, processes for preparing such N,N'-difluorinated diazabicycloalkane derivatives and methods of using such compounds as fluorinating agents. The invention also presents novel N-fluorinated azaazoniabicycloalkane-Lewis acid adduct intermediates which are formed in the processes for preparing such N,N'-difluorinated diazabicycloalkane derivatives.
