近几十年来,有机化学在深度和广度上已达到了一个新的水平. 我们认为在近代有机化学的发展中始终贯穿着二个基本特点,第一是数学和物理学越来越渗入,例如应用计算技术的新实验装置已彻底改变了有机化学结构分析的面目,而且亦使研究工作更为深入和定量;轨道对称守恒原理和前沿轨道理论等量子化学已成为有机化学家新的理论工具。第二个基本特征是生命过程的研究与有机化学密切连系,生物有机化学、生物无机化学、仿生化学、分子生物学等新的边缘学科,蓬勃发展。有机化学工作者正尝试用生命过程中进行的反应来改进原有的有机化学。近代物理有机化学的进展也正从一个重要 In recent decades, organic chemistry has reached a new level in terms of depth and breadth, and we believe that in the development of modern organic chemistry, two basic characteristics have always been followed. The first is the increasing infiltration of mathematics and physics, for example New experimental setups using computational techniques have radically changed the face of organic chemical structure analysis, and have also deepened and quantified research efforts. Quantum chemistry such as the orbital symmetry conservation theory and the orbital orbital theory has become a new theoretical tool for organic chemists. The second basic feature is the close relationship between the research on life process and organic chemistry, and the vigorous development of new edge disciplines such as bioorganic chemistry, bioinorganic chemistry, biomimetic chemistry and molecular biology. Organic chemists are trying to improve their organic chemistry with the reactions that take place in life. The progress of modern physical organic chemistry is also from an important
