Advances in Transition Metal-Catalyzed Silylboration of Methylenecyclopropanes

有机硅/硼化合物在合成化学、新药研发及功能材料领域应用广泛，因此过渡金属催化的亚甲基环丙烷(Methylenecylopropanes, MCPs)直接硅硼化反应成为研究热点。该反应虽具有条件温和、高效及原子经济性高等优点，但多样选择性问题是其发展的主要挑战。本文系统总结了过渡金属催化MCPs的反应及其选择性硅硼化机理，为设计新型不饱和C-C键硅硼化反应提供理论依据，助力高官能度有机硅/硼化合物的选择性合成。Organosilicon/boron compounds are widely used in synthetic chemistry, new drug development, and functional materials, making the transition metal-catalyzed direct silylborylation of methylenecyclopropanes (MCPs) a research hotspot. Although this reaction offers advantages such as mild conditions, high efficiency, and excellent atom economy, the issue of diverse selectivity remains a major challenge for its development. This paper systematically summarizes the reactions of transition metal-catalyzed MCPs and the mechanisms of selective silylborylation, providing a theoretical foundation for designing novel unsaturated C-C bond silylborylation reactions and facilitating the selective synthesis of highly functionalized organosilicon/boron compounds.
