二年多以前,作者曾扼要地介绍过年青的卡宾化学,在此期间,它在各方面又有了迅速的发展,有关的报导在二百篇以上,并有专著问世。本文在前篇的基础上,选择了1961年底前后至1964年初期间卡宾化学进展中的几个重要方面,再作一次介绍和讨论。机理方面的某些问题一个新的概念,开始时往往不易得到普遍的接受或应用,但自普遍接受以后,又可能被一部分人过分强调。卡宾概念的发展,似乎也经历了这样一个过程。在过去若干年中,一方面继续有人用卡宾概念更好地解释 More than two years ago, the author briefly introduced the young Carbide Chemistry. During this period, it also developed rapidly in various fields with more than 200 articles and monographs published. Based on the first part, this article chooses several important aspects in the progress of Carbbin chemistry from the end of 1961 to the beginning of 1964, and then introduces and discusses again. Some of the problems in mechanics A new concept, which is not always easy to get accepted or applied initially, may be overemphasized by some, after its general acceptance. The development of the concept of carbene seems to have gone through such a process. In the past few years, on the one hand, people continue to be better explained by the concept of carbene
