Abstract
The synthesis of well-defined macromolecules using polymerization processes is a challenging and important task in organic chemistry. Palladium-catalyzed cross-coupling reactions represent an important tool in the chemists armory, combining high efficiency, low catalyst loadings, high tolerance to a variety of functional groups and solvents and moderate reaction temperatures (25 – 100 °C). The present review is an account of the recent literature involving Pd-catalyzed, cross-coupling based polymerizations for the synthesis of polythiophenes, as well as the use of this and related compounds in polymer and material science.

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
