摘要: | 路易士酸性已被證實為許多重要的化學反應的關鍵,而在分子上增加正電荷也展現了增強分子酸性與反應性的趨勢。近年來,許多單價及二價主族陽離子展現了催化活性,例如三配位硼陽離子協助的氫化反應及正二價銻化合物催化的矽氫化還原。遵循相同的策略,我們決定合成一系列新穎的具有催化潛力的正二價化合物。基於我們實驗室長期以來對硼陽離子的研究興趣,對於非彈性雙牙配基配位之雙三配位硼陽離子之研究將記錄在本論文中。除此之外,為進一步了解光驅動催化劑之合成,吖取代銻中心之二價陽離子的氧化還原活性也將在本論文中探討。 Lewis acidity has been realized as the key to many useful chemical reactions, and incorporating positive charges into molecules has also shown to enhance Lewis acidities and reactivities of the molecules. Several cationic and dicationic main group compounds have demonstrated catalytic abilities in recent years, such as the borenium assisted hydrogenation and dicationic antimony promoted hydrosilylation. Following the same approach, we decided to prepare a series of novel dicationic compounds with potentials to carry out catalysis. As our long-term interest in cationic boron compounds, several rigid bidentate ligands supported di-borenium dications will be discussed. In addition, to achieve possible photocatalysts, an antimony-based dication bearing an acridine moiety is also synthesized. Its redox property and photostability will also be disclosed. |
