✦ Synopsis


Thechemistry ofpolyfluorinatedketones has recently received a great dealof attention [1 I 21 La]. The carboriyl and imino groups of the fluorinated ketones and their imines react in many different ways. Zn particular, the electron-attracting perfluoroalkyl groups intensify the elecrrophilic properties and weaken the nucleophilic properties of the carbonyl group. The perfluoroalkyl group also hinders the heterolytic removal of the hydroxyl group from adducts c by reducing the stability of the carbonium ion cx. The increased electrophilicity of the carbonylgroup and the increased stability of the addition prod-
