Computational investigations on silicon clusters (Sin) in combination with atomic transition metal (TM) impurities are reviewed in this contribution. Emphasis is placed on studies that focus on the size exohedral to endohedral evolution features of TMSin, such as the critical ligand number for the transition from equilibrium geometry. Geometric, energetic, electronic and magnetic characteristic of TMSin are discussed in the size region n ≤ 20. It is pointed out that selected TMSin systems with n = 12 and n = 16 emerge from present computational research as the most promising candidates for building blocks of novel nanomaterials.

Aromatic heterocycles are ubiquitous building blocks in bioactive natural products, pharmaceutical and agrochemical industries. Accordingly, the carborane-fused heterocycles would be potential candidates in drug discovery, nanomaterials, metallacarboranes, as well as photoluminescent materials. In recent years, the transition metal catalyzed B-H activation has been proved to be an effective protocol for selective functionalization of B-H bond of o-carboranes, which has been further extended for the synthesis of polyhedral borane cluster-fused heterocycles via cascade B-H functionalization/annulation process. This article summarizes the recent progress in construction of polyhedral borane cluster-fused heterocycles via B-H activation.

AbstractTransition-metal-catalyzed C–H bond addition to nitriles has emerged as a powerful synthetic approach for the construction of C–C bonds in organic synthesis. Due to the merits of atom- and step-economy, as well the easy availability of the starting materials, these transformations not only deliver acyclic aryl ketone products with nitriles­ as C-building blocks, but can also be utilized for the highly efficient­ assembly of azaheterocyclic skeletons using nitriles as C–N building blocks. This short review summarizes recent progress on transition-metal-catalyzed C–C bond-forming reactions based on C(sp2)–H and C(sp3)–H additions to nitriles.1 Introduction2 Palladium-Catalyzed C–H Addition to Nitriles2.1 Palladium-Catalyzed C–H Addition to Nitriles for the Preparation of Ketone (Imine) Products2.2 Palladium-Catalyzed C–H Addition to Nitriles for the Preparation of Azaheterocycles2.3 Palladium-Catalyzed C–H Addition to Nitriles/1,2-Rearangement3 Other Transition-Metal-Catalyzed C–H Additions to Nitriles4 Summary and Outlook
