General Aspects

Organozinc species are powerful reagents for performing carbon–carbon and carbon–heteroatom bond-forming reactions in the presence of a transition-metal catalyst. However, extended applications of zinc reagents have been hampered by their moderate air- and moisture­-stability. This short review presents our recent developments on the preparation of solid aryl, benzyl, heteroaryl, allyl zinc pivalates and zinc amide enolate reagents with greatly enhanced stability toward to air and moisture.1 Introduction2 Preparation of Organozinc Pivalates2.1 Using Organic Halides as Substrates2.2 Using a Directed Metalation on Functionalized Arenes and Heteroarenes2.3 Preparation of Solid Allylic Zinc Pivalates3 General Reactivity Patterns of Organozinc Pivalates3.1 General Aspects3.2 Transition-Metal-Catalyzed Cross-Couplings3.3 Other Carbon–Carbon Bond-Forming Reactions Using Organozinc Pivalates3.4 Preparation and Reactions of Solid, Salt-Stabilized Zinc Amide Enolates as New, Convenient Reformatsky Reagents4 Conclusion

Since Geim and co-workers reported their groundbreaking experiments on graphene, research on graphene oxide (GO) and its derivatives has greatly influenced the field of modern physics, chemistry, device fabrication, material science, and nanotechnology. The unique structure and fascinating properties of these carbon materials can be ascribed to their eminent chemical, electronic, electrochemical, optical, and mechanical properties of GO and its derivatives, particularly compared to other carbon allotropes. The present Review aims to provide an overview on the recent developments in the preparation of GO and its derivatives and their applications in organic reactions. We will first outline the synthesis of GO and its derivatives. Then, we will discuss the major sections about their application as stoichiometric and catalytic oxidants in organic reactions, a particular emphasis on the carbon-carbon, carbon-oxygen, and carbon-nitrogen single bond-forming reactions, as well as carbon-oxygen and carbon-nitrogen double bond-forming reactions. Simultaneously, this Review also describes briefly transition metal supported on GO or its derivatives as a catalyst for organic reaction. Lastly, we will present an outlook of potential areas where GO and its derivatives may be expected to find utility or opportunity for further growth and study.
