　　每一个满怀抱负的有机化学家都尝试写出合理的有机反应机理，然而市面上的有关机理正确书写的书籍却寥寥无几。《有机反应机理的书写艺术》将帮助学生和科研人员提高这一重要技能。《有机反应机理的书写艺术》的突出特点体现在：正确的书写形式，“常见错误提示”，配以大量的难度适宜的问题。其另一个特色是包含过渡金属参与或催化的反应章节。相对新的课题，例如，烯烃复分解反应、芳香环化反应等在本《有机反应机理的书写艺术》均有所涉及。
　　全新修订的第2版精彩呈现：更新的反应机理，芳香性的讨论，酸性，立体化学的拓展，重新组织了自由基反应和金属参与或催化的反应等内容，增加了新的问题。

精彩书评

　　“这是一部优秀并完美表达的作品……作者……成功地将反应活性和选择性的核，小观点视为一个有机整体详尽表述简洁的文风，精选的实例……每一章末对要点简明的概括，使得读者很容易巩固学到的知识……这本书不失为一个小小的艺术品。”
　　——Jens Hartung ，Angewandte Chemie International Edition
　　
　　“我使用该书教授学分课程已经三年时间了，学生们一致对本书的透彻叙述和书中试题的覆盖面给予高度赞誉……正如本书的宗旨：教会学生准确写出陌生的有机反应的机理”
　　——Amy Howell，Synthesis
