Q: Why do you think your paper is highly cited?
A: N-heterocyclic carbenes (NHCs) are new, versatile, and very useful ligands in organometallic chemistry and catalysis. This paper collects the information on the synthesis of Ag( I ) N-heterocyclic carbenes, which can be readily prepared and used in order to prepare other potentially very useful transition metal-carbenes.
Q: Does it describe a new discovery, methodology, or synthesis of knowledge?
A: It is a new and easy methodology based on our previous report (Organometallics, Vol.17, 972, 1998), where the Ag( I ) NHCs formed by the reaction of Ag2O with an imidazolium salt were used as carbene group transfer agents to produce metal-NHCs effectively.
Q: Could you summarize the significance of your paper in layman's terms?
A:This paper provides a comprehensive documentation of an important class of silver compounds, which can be easily prepared under ambient conditions. Moreover, the accomplishment of this reaction can be watched with the naked eye.
Q: How did you become involved in this research, and were any problems encountered along the way?
A:The development of this result was not on purpose. While in an attempt to synthesize Au( I )-NHCs using different bases for the deprotonation of azolium salts, the employment of Ag2O as a mild base produced the Au( I )-NHCs effectively. This study implied the generation of Ag( I )-NHCs in situ, and their role as transmetallating agents to prepare other metal-NHCs.

银（I）N-杂环卡宾
Q：你觉得为什么你的论文引用率会这么高？
A: 在有机金属化学和催化化学中，N-杂环卡宾（NHCs）是一类非常有用的新颖的多功能配位体。这篇论文收集了有关银（ I ）N-杂环卡宾合成的信息，银（ I ）N-杂环卡宾非常容易制备和使用，它可用来制备其他有潜在作用的金属卡宾过渡体。
Q: 那对于其他领域，该文章是否描述了一个新发现，新的方法学或合成方面的知识？
A: 我们在先前的论文中(Organometallics, Vol.17, 972, 1998)提到这是一种新的且简便的方法学，由Ag2O 和咪唑盐反应生成的银( I ) NHCs被作为卡宾基团转移体用来高效地合成金属N-杂环卡宾。
Q: 你能用简单的语言概述一下你论文的意义吗？
A: 该论文提供了一个全面的关于银化合物这一重要类别的证据，这类化合物在普通条件下很容易被制备。此外，该合成反应的结果可直接用肉眼判别。
Q: 你是怎样从事你的研究的？在研究过程中遇到过困难吗？
A: 该结论的获得是个意外。当我们试图用不同的去质子唑盐碱液合成金（ I ）N-杂环卡宾时，发现弱碱Ag2O能高效的合成金（ I ）N-杂环卡宾。该研究发现了银（ I ）N-杂环卡宾的原位合成以及它作为转金属因子制备其他金属N-杂环卡宾的作用。
