An efficient and selective introduction of diversified substituents in place of hydrogen is the main task of synthetic organic chemistry. An application of transition metal catalysts has made possible to effect these transformations not only on active C-H bonds amenable to classical methods but also on unactivated C–H sites via its direct activation. Thus, activation of C–H bonds is certainly one of the most rapidly developing research areas in organic chemistry of the 21th century. Although pioneering work in this field dates back to the 1980s, the development of new C–H activation strategies presented herein are one of the most promising and cost-affordable synthetic approaches starting from inexpensive and easily available substrates and towards the valuable organic compounds, which have already found industrial application and high academic interest. The aim of this text is presentation of literature sketch related to the transition metal mediated direct functionalisation of uncreative C–H bonds, especially in its enantioselective version. With the intention to cover all variety of studied field we have tried to make the deliberate selection of rich literature material to isolate the most striking examples of each type of catalytic arylation passing throughout the C–H activation step. Next we compact chosen data in a short review directed primarily towards young generation of chemists and graduate students interested in new promising but yet weakly studied areas of organic synthesis.
