A series of new tetradentate ligands based on the [1.1.1.1]metacyclophane backbone fixed in a 1,3-alternate conformation was achieved. For the strategy developed, the common synthon for the preparation of twelve ligands bearing four interaction sites occupying the apices of a pseudo-tetrahedron [H, SH, CN, SCH3, CO2H, CHO, PPh2, P(O)Ph2, NO2, NH2, pyridine, and para-methoxyphenyl] was the tetrabromo
获得了一系列基于固定在 1,3-交替构象中的 [1.1.1.1] 环芳烃骨架的新四齿配体。对于开发的策略,用于制备带有四个相互作用位点的十二个配体的通用合成子占据假四面体的顶点 [H, SH, CN, SCH3, CO2H, CHO, PPh2, P(O)Ph2, NO2, NH2 、吡啶和对甲氧基苯基]是四溴衍生物 7。除了适用于所有报道的配体的经典表征方法外,化合物 7、9、12 和 13 还在固态下通过单晶 X 射线进行结构研究衍射,这确实证实了它们的 1,3-交替构象。
