【正文】 越來越多有機甚至無機化學家們的關(guān)注,他們使用各種各樣的辦法來促進催化、提高反應產(chǎn)率、簡化反應的步驟等等。本論文研究的納米碘化亞銅的催化性能,是對銅催化反應一個很好的改進,同時為銅催化的反應開發(fā)其他配體提供了參考。銅催化的反應的研究工作畢竟只是有機化學、綠色化學中的一小部分,并且我們對其反應機理的研究還不是很成熟,我們面臨的挑戰(zhàn)和機遇是并存的,希望本文中列舉的一些結(jié)果和分析能夠起到秉承傳接的作用,使納米銅催化反應方面的研究能夠更加繁榮。致 謝本論文是在許華建博士和馮乙巳教授的悉心指導下完成的。許老師和馮老師對待工作勤奮敬業(yè)、待人處事寬容謙和、培養(yǎng)學生嚴禁不茍的精神給我留下了深刻印象,并潛移默化地影響著我的一生。他在科研上的創(chuàng)新意識和開放思維,使我在本課題的研究工作受益匪淺。在此,謹向他表示崇高的敬意和衷心的感謝!其次要感謝梁玉峰學長、蔡振亞學長、萬薪學姐、吳偉學長、張博學長、張家松學長以及707的其他各位師兄師姐,他們在課題的研究中給予了我許多的意見和幫助,提出了許多開創(chuàng)性的想法,同時還傳授了我許多實驗的經(jīng)驗和操作方法,使我對縱向課題的研究有了較為深入的了解。同時還要感謝何建勛、耿燁、俞建斌等同學,他們在實驗過程中也給予了我很多的幫助。最后,謹以此文獻給我的父母,他們是我多年求學的動力,給予了我最無私的支持、理解和鼓勵。參考文獻[1](a)Prim,D。Campagne,.。Joseph,D.。Andrioletti,58,2041.(b)Ley,.。Thomas,42,5400.[2]Ullmann,34,2174.[3]Ullmann,36,2382.[4]Hartwig J metal catalyzed synthesis of arylamines and aryl ethers from aryl halides and triflates:scope and Chem,Int Ed,1998, 37(15):20462067.[5]Kunz K,Scholz U,Ganzer D.
