The Preparation of Imidoyl Fluorides

Rowe, Jeffrey E.,Lee, Kam,Dolliver, Debra D.,Johnson, James E.

, p. 807 - 812 (2007/10/03)

The first general synthesis of imidoyl fluorides is reported here. Irradiation of the initially formed Z isomers of N-methoxybenzenecarboximidoyl fluorides led to a photoequilibrium containing both the E and Z isomers. The pure E isomers were able to be isolated from these isomeric mixtures. The n.m.r. spectra of these isomers are discussed.
