Abstract
A Crabtree-type Ir(I) complex tagged with a fluorescent dye (bodipy) was synthesized. The oxidative addition of H2 converts the weakly fluorescent Ir(I) complex (Φ=0.038) into a highly fluorescent Ir(III) species (Φ=0.51). This fluorogenic reaction can be utilized for the detection of H2 and to probe the oxidative addition step in the catalytic hydrogenation of olefins.
摘要
合成了一种带有荧光染料（bodipy）的 Crabtree 型 Ir(I) 配合物。H2 的氧化加成将弱荧光 Ir(I) 配合物（Φ=0.038）转化为强荧光 Ir(III)物种（Φ=0.51）。这种荧光反应可用于 H2 的检测，并可用于探测烯烃催化氢化中的氧化加成步骤。
