N,N-Bis(trifluoromethyl) amidosulfonyl fluoride and lower fluorinated
analogues can be obtained by electrochemical fluorination as well as b
y CoF3-fluorination of N,N-dimethylamidosulfonyl fluoride or chloride.
The CoF3 process is especially useful for the synthesis of lower fluo
rinated compounds. The new compounds are potential insecticides.
