据报道，获得一系列官能化五螺旋烯的最短、最有效的路线之一。苄基（二溴）次甲基偶联是功能性螺烯化学的重要组成部分。它允许通过一些金属催化的 Ar-C、Ar-S、Ar-CN 和 Ar-I 键形成进行单或双官能化。这些功能为进一步的应用提供了新的途径。例如，螺旋烯 (4) 可以支撑在 Ag(001) 表面上，其特征在于高分辨率 NC-AFM 成像。
One of the shortest and most efficient routes toward a series of functionalized pentahelicenes is reported. Benzylic (dibromo)methine coupling is an important entry into functional helicene chemistry. It allowed a mono- or a double functionalization by some metal-catalyzed Ar-C, Ar-S, Ar-CN, and Ar-I bond formations. Those functions offer new avenues for further applications. For instance, helicene (4) can be supported on a Ag(001) surface, which was characterized by high-resolution NC-AFM imaging.
