1、化学专业英语演讲有机化学发展史Development of organic chemistry and its impact on the development of science and technology有机合成的发展及其对科有机合成的发展及其对科学技术发展的影响学技术发展的影响First part : A brief historyPhase One: Infancy (Early 19th century - 1858) Chemical development of this period is the basis for the development of organic
2、chemistry. Lavoisier is known as the father of modern chemistry. Phase Two: Classic Period (1858-1916) During this period the emergence of a large number of well-known organic chemist.Figure character is a famous organic chemist Kekule and Vant Hoff. Phase III: Modern Age Organic Chemistry (1916 to
3、date) This is the theoretical basis of organic chemistry more perfect time.The most famous organic chemist is Woodward in this period , he was known as the father of modern organic chemistry. Second part: Advances in Organic Synthesis Organic Chemistry is a very important chemical sciences in the tw
4、o disciplines, is most closely associated with the chemical branch of human life, its development and the development of human society are closely related.(1)Reactions and synthesis metal participatingCH bond activation In addition to palladium and other precious metals rhodium catalyzed carbon-hydr
5、ogen bond activation【1,2,3】, the use of relatively inexpensive copper, iron and other metals to achieve carbon-hydrogen bond activation has also been a great concern. Such as N Jiao【4】realized copper-catalyzed aniline ortho CH bond activation to introduce an azide group.The coupled reaction L Liu by
