ABSTRACT:
N,N-difluoroamines are prepared by fluorination of compounds containing a >C.dbd.N-- bond using molecular fluorine or a hypofluorite in which the fluoroxy group is bonded to an inert electron attracting group, such hypofluorites including fluoroalkyl hypofluorites such as trifluoromethyl hypofluorite. The fluorination is advantageously conducted in the presence of an alkanol or other nucleophilic compound. Suitable starting materials include imino ethers and esters and aliphatic and aromatic Schiff's bases, use of the latter being particularly convenient.
