Electrochemical fluorination (ECF) has been examined for six aliphatic secondary amines: N, N-di-ethylamine, N-ethyl, Nn-propylamine, N, N-di-n-propylamine, N-ethyl, N-iso- propylamine, N, N-di-iso-propylamine, and N-methyl, Nn-butylamine. It was found from these amines that not only the corresponding F-(N-fluoro-N, N-dialkylamines) but also F-imines having the same number of the carbon atoms were formed in low yields. The suppression ...
