    • The synthesis of para- phenylene oligomers encapped with diphenylamine and studies of their photophysical and electronic properties are mentioned in this dissertation. Gold catalyzed [2+2+2] cycloaddition of ynamides and cross coupling of tow carbene generated from different sources to form dienes are detailed in this dissertation. A novel multicomponent reaction involving benzyne, an N-oxide and an alkyne is also described in this dissertation. For sake of convenience and better understanding, the thesis is divided into four chapters.

    In the first chapter a regiocontrolled synthesis of ethylene bridged para phenylene oligomers encapped with two aryl amines with varied spacer lengths is explained. We also presented and explained the variations of the photophysical and electronic properties of this set of para phenylene oligomers in particular their HOMO-LUMO energy levels, UV absorptions, and fluorescent emissions and quantum yields.

    The second chapter deals with a novel gold catalyzed [2+2+2] cycloaddion reaction of aryl amides with enol ethers. Particularly notable is the cycloaddition has no precedent in an intramolecular version. This reaction proved to be an efficient way for the synthesis of cyclohexenes.

    The third chapter describes the synthesis of dienes via gold catalyzed crosscoupling of carbenes arising from two different sources, a vinylcarbene fragment resulting from a propargylic ester rearrangement and a diazoalkane carbene.

    The fourth chapter presents a metal free novel muticomponent reaction involving benzyne, Pyridene N-oxide and an alkyne.

    本篇論文可分為四個章節，第一章節為合成一系列線形多苯環化合物且於分子之頭尾兩端接上二苯胺分子，並進一步測量以及探討其特殊的光物理以及電化學性質。第二以及第三章節主要利用金金屬錯合物催化 ynamides 分子進行[2+2+2] 環化加成反應以及利用碳烯分子進行交叉耦合反應合成一系列二烯類化合物。最後第四章節利用苯炔化合物、氧化胺以及炔分子進行多化合物組成反應合成一系列苯基吡啶化合物。

    第一章節我們利用了不同的金屬錯合物催化具有高度位向選擇性之環化反應，將線型對苯化合物以乙烯分子橋接起來，並於兩端引入了二苯胺分子合成了一系列不同長度的線形多苯環分子。經由測量其HOMO、LUMO、UV吸收光譜、 螢光放射光譜 以及量子產率，實驗中發現此系列分子具有特殊的光物理以及電化學性質。

    第二章節中我們開發了新型的金金屬錯合物催化芳酰胺分子以及烯醚化合物進行[2+2+2] 環化加成反應，值得注意的是此類新型反應並沒有觀察到任何分子內反應發生，可以利用於合成一系列的環己烷化合物。

    第三章節我們發展了利用炔酯類分子進行重排反應以及重氮烷基碳烯產生乙烯基碳烯再經由金金屬錯合物催化交叉耦合反應。

    最後一個章節我們利用了苯炔化合物、氧化胺以及炔分子進行多化合物組成反應合成一系列苯基吡啶化合物。
