  • 本研究使用實驗室所開發的鈷水合錯合物[CoIIIBDPP(H2O)]BF4 (2),加入過氧氫化異丙苯(cumene hydroperoxide)會形成鈷過氧烷化物CoIIIBDPP(OOCm) (3)。將2 -苯基丙醛(2-phenylpropionaldehyde , 2-PPA)加入至錯合物3,利用GC-MS可偵測到產物苯乙酮的生成。本研究也延續陳廷奕學長的研究,將鈷過氧氫化物CoIIIBDPP(OOH) (6)氧化,並與鈷超氧化物CoIIIBDPP(OO˙) (4)質子化的UV-vis與EPR光譜做比較。我們也嘗試將錯合物3和鈷過氧化物(K-cryptand)[CoIIIBDPBrP(OO)] (7’)氧化,並利用UV和EPR光譜追蹤其變化。

    In this study, the cobalt(III) complex [CoIIIBDPP(H2O)]BF4 (2) was prepared for the further synthesis, and the cumene hydroperoxide was added to form the cobalt alkylperoxo complex CoIIIBDPP(OOCm) (3). 2-Phenylpropionaldehyde (2-PPA) was then added to complex 3, and the formation of the product, acetophenone, was detected by GC-MS. This study also continues the research of the senior member Ting-Yi Chen. The UV-vis and EPR spectra of the oxidized cobalt(III) hydroperoxo complex, CoIIIBDPP(OOH) (6), are very similar to those of the protonation of the cobalt superoxo complex CoIIIBDPP(OO ̇) (4). We also attempted to oxidize Complex 3 and the cobalt peroxo complex (K-cryptand)[CoIIIBDPBrP(OO)] (7’), and track its changes by using UV and EPR spectra.
