1, 3二羰基化合物可經由過渡金屬氧化形成自由基，然後與烯類進行加成反應。此類方法已被研究多年，而且可以合成出一些天然物的骨架。然而1, 3二羰基化合物與富烯的反應卻沒有相關的報導。本篇論文即要探討利用碳酸銀促進1,3二酮對富烯的氧化加成反應。此外並發現碳酸銀可以促進1, 3-環己二酮的偶合形成二聚物，接著與富烯作用可以一步得到四環的加成產物。這個特殊的反應也許可以應用在天然物的合成上。

Oxidative addition of 1,3-dicarbonylalkyl radicals mediated by transition metals to alkenes to afford the dihydrofurans have received a lot of attention over the years. However, reaction of 1, 3-diketone to fulvene has never been realized. In this thesis, Ag2CO3 was used as oxidantin the reaction of 1,3-diketones and fulvenes. As the result , we have developed a methodology of one-pot Ag2CO3 mediated oxidative dimerization of 1,3-diketone followed by cycloaddition to fulvenes that provide 7-oxatricyclo[6,4,0,02,6]dodecane and/or 8-oxatricyclo[7,4,0,03,7] tridecanes.
