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学技术发展的影响,First part:A brief history,Phase One:Infancy(Early 19th century-1858)Chemical development of this period is the basis for the development of organic chemistry.Lavoisier i
2、s 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 date)This is the theoretica
3、l 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 two disciplines,is most closely a
4、ssociated with the chemical branch of human life,its development and the development of human society are closely related.,Reactions and synthesis metal participatingCH bond activation In addition to palladium and other precious metals rhodium catalyzed carbon-hydrogen bond activation【1,2,3】,the use
5、 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 copper-catalyzed realized an alkyl h
