Abstract
The generation of perfluoroalkyl radicals (RF•) by means of photocatalysis is a more suitable route than the established methods employing chemical initiators, like azo or peroxide compounds or the use of transition metals. Conditions governed by photocatalysis can allow for a wide range of functional groups and, therefore, can be applied to the latestage transformation of bioactive molecules. Organic photocatalysts (POC), in the absence of transition metals, can suffer electron-exchange reactions, yielding RF radicals. RF radical production without the assistance of transition metals through the employment of POC will be described, applying this methodology to studying classical examples.
Keywords: Photo-organocatalysis, fluoroalkyl radicals, organic dyes.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
