From the first N₂-metal complex discovered in the 1960s to the borylene N₂ complex reported very recently, chemists have been trying to activate N₂ under milder conditions by investigating many approaches or strategies. Among them, carbene species has been considered a good choice to construct N–C bond to obtain N-containing organic compounds directly. Since the first glimpse of the N₂ exchange of diazomethane, chemists have obtained a deeper understanding of the rebound reaction between carbene and N₂. This review mainly summarizes the progress in the field of N₂ fixation by using carbene species, both experimentally and theoretically. We believe this review will provide readers with an in-depth understanding of the state-of-the-art and perspectives of future research particularly in the use of carbene species for activation and transformation of N₂ into N–C containing organic compounds.

从1960年代发现的第一个N _2-金属络合物到最近报道的硼化N ₂络合物，化学家一直在通过研究许多方法或策略试图在较温和的条件下活化N ₂。其中，卡宾物种被认为是构建N–C键以获得直接含氮有机化合物的好选择。自从第一眼看到重氮甲烷的N ₂交换以来，化学家就对卡宾与N ₂之间的反弹反应有了更深入的了解。这篇综述主要总结了N ₂领域的进展。在实验和理论上通过使用卡宾物质进行固定。我们相信这篇评论将为读者提供对最新技术和未来研究前景的深入理解，特别是在使用卡宾物种活化N ₂并将其转化为含N–C的有机化合物方面。
