摘要

以“- cf2o -”为单元的全氟烷基醚羧酸盐（peca盐）为含氟试剂，开发了一锅法将脂肪族和芳族叔胺转化为新型氟化胺酮。通过这些pfea盐的热分解，提出了羰基氟化物、酰氟化物和酸酐作为关键活性物质，通过烯胺中间体触发叔胺的连续氧化-酰化过程。

Synthesis of trans-2-(Disubstituted-amino)alkenyl Polyoxyperfluoroalkyl Ketones from Tertiary Amines and Perfluoroalkyl Ether Carboxylates Featuring “–CF2O–” Units†

A one-pot transformation of aliphatic and aromatic tertiary amines to novel fluorinated enaminones has been developed, utilizing perfluoroalkyl ether carboxylates (PFECA salts) featuring “–CF₂O–” units as the fluorine-containing reagents. Carbonyl fluoride, acyl fluorides and anhydrides by thermal decomposition of these PFECA salts were proposed to act as key active species that trigger the tandem oxidation–acylation process of tertiary amines, through enamine intermediates.
