摘要

無機材料稼接鈀金屬錯合物近幾年來已漸漸成為有機催化合成上一個重要的課題，尤其是具有高表面積和化學穩定性佳的二氧化矽奈米孔洞材料；本文中將簡述幾種發展成熟且合成簡易的中孔洞二氧化矽材料，並研究利用此種材料作為非均相催化擔體，進行有機合成催化反應，如：(1) Suzuki-Miyaura Reaction、(2) Mizoroki-Heck Reaction、(3) Sonogashira Reaction等與其他相關的有機催化反應，同時也探討催化劑的再回收與金屬觸媒在反應中流失現象。

Immobilization of palladium complexes on inorganic materials has been an important potential class for organic catalytic reactions; particularly mesoporous silica materials possess advantages with high surface area and excellent chemical stability. This brief review introduced several mature and cheap mesoporous silica materials, and focused on the preparation and application of such heterogeneous supports grafted palladium complexes for the carbon-carbon cross-coupling reactions, such as (1) Suzuki-Miyaura Reaction, (2) Mizoroki-Heck reaction and (3) Sonogashira reaction, etc. The recyclability and leaching test of the heterogeneous catalysts will also be discussed.
