Iridium trisboryl complexes containing bisphosphine and bipyridine ligands and pinacolate and catecholate substituents on boron are reported. A large difference in reactivity towards the borylation of C-H bonds is observed for this series of trisboryl complexes, and this difference is attributed to the electron-donating properties of the pinacolate vs. catecholate groups, and the steric and electronic properties of bipyridine vs. bisphosphine ligands.
报道了含有双膦和联吡啶配体以及硼上的频哪醇和儿茶酚取代基的三硼铱配合物。对于这一系列三硼配合物，观察到其对C-H键硼化反应的反应性存在很大差异，这种差异归因于频哪醇基团与儿茶酚基团的给电子性质，以及联吡啶配体与双膦配体的空间和电子性质。
