Activation reactions of Ru-catalyzed arylic or olefinic C-H bonds

In the last few years, much has been learned about the transition metal catalyzed activation of arylic or olefinic C-H bonds. An important extension of these reactions such as C-H/olefin, C-H/acetylene, C-H/CO and C-H/CO/olefin couplings, hydroacylation and silylation can be regarded as practical tools, for these reactions exhibit high selectivity, high efficiency and wide applicability. Especially the C-H/CO/olefin coupling protocol can be a useful complementary method to Friedel Crafts reaction, since it takes place even when there're electron withdrawing groups in the aryl groups of substrates. In these reactions the coordination of the substrates to the ruthenium center in the catalyst complex is a necessary prerequisite for the reactions to proceed. In this paper, we'll survey the Ru catalyzed functionalizations of C-H bonds that were published up to the end of 2000. These catalytic reactions involve a step of nucleophilic addition by a ruthenium complex. The factors affecting the selectivity shown by different catalysts are also discussed.
