In recent years, transition-metal-catalyzed C–H functionalization has emerged as a potentially greener alternative to classic cross-couplings and as a powerful tool to access complex functional molecules with improved step-economy. This short account relates our experience of industrial collaborations in C(sp3)–H bond activation, which were key to the development of this topic in our group. The synthesis of the antianginal drug Ivabradine led us to develop a general approach to benzocyclobutenes, which were further employed in peri cyclic reactions. A follow-up study led us to discover a new method to construct arylcyclopropanes via double C–H activation and the coupling of two alkyl groups. Finally, targeting the herbicide Indaziflam contributed to develop C(sp3)–H activation as a powerful tool to access a variety of relevant indane motifs. We hope that these successful stories will help to stimulate further fruitful Industry-Academia collaborations in the field of synthetic chemistry.

Chemical transformations via catalytic C–H bond activation have been established as one of the most powerful tools in organic synthetic chemistry. Transition-metal-catalyzed direct functionalization of β-C(sp3)–H bonds of carbonyl compounds has been developed in recent years. This highlight will focus on recent advances in this active area and their mechanisms are also discussed.

Carbon-carbon bond formation by transition metal-catalyzed C–H activation has become an important strategy to fabricate new bonds in a rapid fashion. Despite the pharmacological importance of <i>ortho</i>-arylbenzylamines, however, effective <i>ortho</i>-C–C bond formation from C–H bond activation of free primary and secondary benzylamines using Pd<sup>II</sup> remains an outstanding challenge. Presented herein is a new strategy for constructing <i>ortho</i>-arylated primary and secondary benzylamines mediated by carbon dioxide (CO<sub>2</sub>). The use of CO<sub>2</sub> is critical to allowing this transformation to proceed under milder conditions than previously reported, and that are necessary to furnish free amine products that can be directly used or elaborated without the need for deprotection. In cases where diarylation is possible, a chelate effect is demonstrated to facilitate selective monoarylation.

Bicyclic alkenes, including Oxa- and azabicyclic alkenes can be readily activated by using transition-metal complexes with facial selectivity, because of the intrinsic angle strain on carbon-carbon double bonds of these unsymmetrical bicyclic systems. During last decades considerable progress has been done in the area of ring-opening of bicyclic strained ring by employing the concept of C-H activation. This Review comprehensively compiles the various C-H bond activation assisted reactions of oxa- and azabicyclic alkenes, viz., ring-opening reactions, hydroarylation as well as annulation reactions.
