Recent investigations have shown that cycloaddition reactions, widely used in organic chemistry to form ring compounds, can also be applied to link organic molecules to the (001) surfaces of crystalline silicon, germanium, and diamond. While these surfaces are comprised of Si=Si, Ge=Ge, and C=C structural units that resemble the C=C bonds of organic alkenes, the rates and mechanisms of the surface reactions show some distinct differences from those of their organic counterparts This article reviews recent studies of [2 + 2], [4 + 2] Diels-Alder, and other cycloaddition reactions of organic molecules with semiconductor surfaces and summarizes the current understanding of the reaction pathways.
最近的研究表明，环加成反应在有机化学中广泛用于形成环状化合物，也可用于将有机分子连接到晶体硅、锗和金刚石的(001)表面。虽然这些表面由类似于有机烯烃的C = C键的Si = Si、Ge = Ge和C = C结构单元组成，但表面反应的速率和机理与有机对应物的速率和机理存在一些明显差异。本文综述了有机分子与半导体表面的[2 + 2]、[4 + 2]狄尔斯-阿尔德和其他环加成反应的最新研究，并总结了目前对反应途径的理解。
