Abstract
An iridium photocatalyst enables the addition of fluorinated groups to nitrones using ascorbic acid as a stoichiometric reducing agent. Partially fluorinated alkyl iodides can also be effectively used. The resulting hydroxylamines can be readily converted to valuable fluorinated amines by reduction with zinc.
