Fluorinated Ketenimines

Methods of obtaining imines of fluorinated ketens are surveyed, together with their dimerisation and nucleophilic addition. Cycloaddition at the carbon–nitrogen bond and 1,4-dipolar cycloaddition involving the aromatic ring are most characteristic of fluorine-containing N-arylketenimines. A two-stage mechanism is suggested, involving intermediate formation of small rings.
The Review concludes with 92 references.
