Abstract
Graphene is a new and hot research topic due to properties previously not observed on the nanoscale. These properties make graphene a promising candidate for new devices. However, graphene is not soluble, and this property limits its processability. Therefore, chemical functionalization is needed. This short review summarizes the covalent chemical reactions that have been performed on individual graphene sheets – the production of graphene oxide with subsequent transformation to graphene, the covalent modification of graphene oxide functional groups and the surface chemistry of the aromatic rings of graphene sheets.
Keywords: Graphene, graphite, graphene oxide, oxidation, reduction, modification, surface chemistry, allotropes, nanotubes, feeble acid reaction, hydrophilicity, thermal decomposition, endothermic effect, dehydration

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
