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.

協同效應是近年來經常看到和聽到的一個化學研究方法或者策略。通過協同效應，可以實現其它方法難于實現或者不能實現的化合物的合成或者合成方法。本實驗室自1999年開始，首先認識到并提出了雙金屬有機合成試劑（如雙锂試劑）及其協同效應。應Springer出版社的邀請，我們主編了Topics in Organometallic Chemistry 系列專輯之一“Organo-di-Metallic Compounds (or Reagents): Synergistic Effects and Synthetic Applications”《雙金屬有機試劑：協同效應與合成應用》。本專輯邀請相關領域的五個代表性課題組介紹了不同類型的雙金屬有機化合物的協同效應及其在有機合成化學中的獨特應用。
本專輯的主要目的是通過展示雙金屬有機合成試劑的獨特結構和協同效應，激發創新合成方法或者合成策略。
