摘　　要：铀化物的合成已成为金属有机化学领域的研究热点之一。相比于过渡金属化合物,铀化物的合成与分离极具挑战性,尤其是包含铀碳键化合物。碳卡宾具有孤对电子易与铀的空轨道成键,而苄基或烷基中的碳无孤对电子,难以与铀结合,所以饱和碳配体铀化合物的研究较少。随着人们对铀独特的电子结构与成键性质的研究,基于饱和碳配体铀化合物研究取得了一些进展。本综述系统总结了饱和碳配体与不同价态的铀(+3、+4、+5和+6)形成化合物的结构以及成键性质。The synthesis of uranium compounds has become one of the hot fields in organometallic chemistry.Compared with transition metal compounds,the synthesis and isolation of uranium compounds is extremely challenging,especially for the ones bearing uranium-carbon bonds.Carbene has lone pair electrons that easily combine with the empty orbitals of uranium.However,the carbon of benzyl or alkyl groups has no lone pair of electrons,which makes it difficult to combine with uranium.With the understanding of the electronic structure and bonding properties of uranium,some progress has been made in the study of uranium compounds coordinated with saturated carbon.This review systematically summarizes the structures and bonding properties of different valence states uranium compounds.
