膦氧导向钯催化邻碳硼烷Heck类型的官能团化反应

Phosphine Oxide-Directed Palladium-Catalyzed Heck-Type Functionalization of o-Carboranes

邻-碳硼烷的选择性官能团化是碳硼烷化学中的一个热点.由于邻-碳硼烷特殊的三维芳香性,其在聚集诱导发光材料、非线性发光材料以及其他功能材料领域有着广泛的应用.在邻碳硼烷上引入π-共轭体系能进一步扩大其在发光材料领域的应用.报道了膦氧导向钯催化邻碳硼烷 Heck 类型的单烯基化反应.

The selective functionalization of o-carboranes is a popular topic in carborane chemistry.o-Carborane has been widely used in aggregation-induced luminescent materials,nonlinear luminescent materials and other function materials due to its special 3D-aromaticity.The π conjugated systems-tethered o-carboranes could further broaden its applications in the field of luminescent materials.Herein,we have developed a palladium-catalyzed Heck-type mono-alkenylation of o-carboranes featuring phosphine oxide as the directing group.
