Photochemical reactions of fluoro-substituted ketones with amines, tetraphenylborates, and organometals: an electron spin resonance study

Ammonium ion-pairs, solvent-separated alkali-metal ion-pairs, and Group IVB organometallic adducts of fluoro-substituted ketones were generated photochemically. The structure and the controlling factors for the formation of contact ammonium ion-pair were deduced from the effects of solvent, amine, and fluorine substitution. The effect of fluorine on the formation of the alkali-metal ion-pairs and organometallic adducts was discussed.
