| dc.description.abstract | 硼陽離子是一種高度缺乏電子的線性雙配位硼陽離子，一般都需要兩個具有-推電子性質之氨基來穩定，反應性研究也相對少。近期研究報導指出二芳基苯雙配位硼陽離子（[Mes2B]+）可與二氧化碳、氫氣、二苯乙炔、矽烷等反應，且反應模式與較穩定的三配位硼陽離子不同，所以在過去幾年中受到了相當多的關注。然而，在所有報導的二芳基雙配位硼陽離子的反應中觀察到，所有反應皆與芳基-硼鍵的斷裂相關，顯示此類化合物並不具有潛在的催化應用。為了探究如何可以讓雙配位硼陽離子可以具有催化應用，我們決定研究芳基氨基取代之雙配位硼陽離子[Ar-B+-NR2]的合成，並探討此類化合物的催化潛力。在本論文中，我們成功合成了一個穩定的、具有C–B–N結構的二配位硼陽離子[Mes-B-TMP] [B(C6F5)4]，並將其應用於酮和醛的矽氫加成、矽氰加成、以及硼氫加成反應上。 初步結果表明，羰基與硼陽離子的配位反應會降低硼陽離子的催化活性，顯示催化反應的活化步驟不涉及羰基對硼陽離子的配位。 | zh_TW |
