摘要 众所周知,在有机催化反应中经常用到不同的有机或无机碱,许多碱本身也可以作为催化剂,但化学家们对碱在化学转化中的作用并没有系统和明确的认识,许多反应中碱的选择都是经过大量的条件实验确定的.针对这些问题,席振峰课题组对文献中碱的作用进行了系统归纳和总结,分析了碱的多种因素对反应的影响并提出了一些规律性的结论,对理解碱效应具有很高的参考价值. Organic and inorganic bases have been widely employed in many metal-catalyzed organic reactions to promote the catalytic efficiency and improve the selectivity. In many cases, a certain base only works well for one type of reactions and roles of the base cannot be clearly understood at present. Professor Xi's group at Peking University recently summarized the roles of bases in many catalytic transformations and discussed the possible factors of bases on these transformations. This is the first review article on the systematic analysis of the base effects. This highlight, based on this review and the related references, will briefly discuss base effects on catalytic organic transformations.
