A new book to be released:
Organo-di-Metallic Compounds (or Reagents):
Synergistic Effects and Synthetic Applications
Dianions present in the same derivative frequently appear as important synthetic intermediates, and often show synergistic effects inside the same molecule and toward useful transformations of substrates. This volume deals with dianionic compounds which contain carbon anions with various metals (such as Li, Mg, Ca, Ba, Al, Fe, Zn, Cu, rare earth metals, etc.). Synthesis and structures of dianionic compounds containing two identical or different metals are briefly introduced. Their synthetic applications based on their synergistic effects are focused especially on making organic compounds and organometallic compounds via novel improved processes.
Five research groups with expertise in the field summarize recent fascinating developments, including 1,4-dilithio-1,3-butadienes and their transmetallated organo-di-metallic compounds, mixed dimers of lithium amide/alkyllithium, gem-diorganometallic compounds, alkali-metal mixed-metal ate compounds, and lithium zincates.
The primary purpose of this volume is to demonstrate the unique structures and synthetic innovations of organo-di-metallic compounds and to initiate new ideas leading to further synthetic strategy in the future. This volume should be useful to researchers in organic and organometallic chemistry, and catalysis both from academia and industry. Moreover, young researchers, doctorate students and post doctoral researchers should be motivated by these innovations in chemistry.
I gratefully acknowledge the cooperative contributions by all authors. Without their expertise and efforts this volume would not have been possible. I would also like to thank Prof. Dixneuf for his encouragement and help throughout the preparation of this volume.

协同效应是近年来经常看到和听到的一个化学研究方法或者策略。通过协同效应，可以实现其它方法难于实现或者不能实现的化合物的合成或者合成方法。本实验室自1999年开始，首先认识到并提出了双金属有机合成试剂（如双锂试剂）及其协同效应。应Springer出版社的邀请，我们主编了Topics in Organometallic Chemistry 系列专辑之一“Organo-di-Metallic Compounds (or Reagents): Synergistic Effects and Synthetic Applications”《双金属有机试剂：协同效应与合成应用》。本专辑邀请相关领域的五个代表性课题组介绍了不同类型的双金属有机化合物的协同效应及其在有机合成化学中的独特应用。
本专辑的主要目的是通过展示双金属有机合成试剂的独特结构和协同效应，激发创新合成方法或者合成策略。
