Studies on the direct fluorination of the acidic imide (CF3SO2) 2NH and of its lithium salt (CF3SO2) 2NLi have enabled us to establish a potentially-viable commercial route to N- fluorobis (trifluoromethanesulfonyl) imide,(CF3SO2) 2NF, and to carry out hazard testing on this well-known electrophilic fluorinating agent.
