Abstract DBU-CH3I has been poised to be a substitute for diazomethane in the preparation of methyl esters from carboxylic acids. The reactions can be carried out in commercial untreated acetone and acetonitrile, which have been exemplified with several methyl esters, otherwise it is difficult to prepare. Bis-esterification using diiodomethane can also be achieved in a similar fashion. Sufficiently
摘要 DBU-CH3I 已准备好在由羧酸制备甲酯中替代重氮甲烷。反应可以在商业未处理的丙酮和乙腈中进行,已经以几种甲酯为例,否则很难制备。使用二碘甲烷的双酯化也可以类似方式实现。足够酸性的酚也可以方便地通过该方法O-甲基化。
