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.
N,N-二氟胺是通过使用分子氟或含有氟氧基与惰性电子吸引基团结合的次氟酸盐对含有>C.dbd.N--键的化合物进行氟化制备的,这些次氟酸盐包括三氟甲基次氟酸盐等。氟化反应在存在烷醇或其他亲核化合物的情况下有利地进行。适合的起始物质包括亚胺醚和酯以及脂肪和芳香亚胺碱,后者的使用特别方便。
