Photoinduced Metal-Free Decarboxylative Fluoroalkylation of Alkenes for the Synthesis of N-Arylbutanamides and Oxindoles.

ABSTRACT

The visible light-induced decarboxylative cascade reaction of fluoroalkyl carboxylic acids has been achieved for the efficient synthesis of fluorinated compounds. However, most of the transformations rely on noble iridium metal complex. Herein, a visible light-induced metal-free decarboxylative cascade reaction of fluoroalkyl carboxylic acids has been realized. This protocol features simple operation, transition metal free, and good functional group tolerance.
