In this paper we present a simple and efficient two-step procedure for the preparation of triformylmethane from bromoacetic acid and dimethylformamide, synthesis of some triformylmethane derivatives of preparative importance, evidence for an intramolecular hydrogen bond in triformylmethane, based on its 1H-NMR spectra measured in deuterochloroform in the presence of trichloroacetyl isocyanate, and comments on some recent erroneous statements1 concerning the IR spectra of triformylmethane.
在本文中,我们提出了一种简单而高效的两步法,利用
溴乙酸和二甲基甲酰胺制备三甲酰
甲烷,并合成了一些具有重要制备价值的三甲酰
甲烷衍
生物。同时,我们基于在
氘代氯仿中测得的1H-NMR谱在
三氯乙酸异氰酸酯存在下,提供了三甲酰
甲烷内部氢键的证据,并对近期有关三甲酰
甲烷红外光谱的一些错误陈述进行了评论。
