AbstractSeveral approaches toward electrophilic C–H silylation of electron-rich arenes are discussed, comprising transition-metal-catalyzed processes as well as Lewis-acid- and Brønsted-acid-induced protocols. These methods differ in the catalytic generation of the silicon electrophile but share proton removal in form of dihydrogen. With slight modifications, these methods are often also applicable to the related electrophilic C–H borylation.

The diverse methodologies to synthesize N-heterocycles through transition-metal-catalyzed cascade addition/cyclization of a nitrile are discussed in this review. Aspects relating to three types of transition-metal-catalyzed addition of a nitrile with subsequent cyclization include (1) a transition-metal acting as a Lewis acid to accelerate the nucleophilic addition of a nitrile, (2) the late-transition-metal-catalyzed 1,2-insertion of a nitrile, and (3) an in situ generated radical by transition-metal catalysis to implement a radical addition/cyclization tandem reaction. Applications for the synthesis of natural alkaloids, their derivatives, and some bioactive compounds are also summarized herein.1 Introduction2 Nucleophilic Addition of a Nitrile Accelerated by a Lewis Acid2.1 Late-Transition-Metal Catalysis2.2 Early-Transition-Metal Catalysis2.3 Lanthanide-Metal Catalysis2.4 Cyclization from N-Arylnitriliums3 Transition-Metal-Catalyzed Insertion of a Nitrile4 Transition-Metal-Catalyzed Radical Addition of a Nitrile5 Conclusions
