Borane Cluster

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.

Remarkable Progress

Transition-metal-catalyzed cross-couplings have been recognized as a powerful tool for sustainable syntheses. Despite the fact that remarkable progress was achieved by palladium and nickel catalysis, the high price and toxicity still remained a drawback. Recently, naturally more abundant and less toxic low-valent chromium salts, such as Cr(II) and Cr(III) chlorides, displayed notable unique catalytic reactivity. Thus, recent progress in the field of chromium-catalyzed cross-couplings and related reactions are highlighted in the present short review until December­ 2018.1 Introduction and Early Chromium-Mediated Reactions2 Chromium-Catalyzed Cross-Couplings and Related Reactions3 Conclusion
