摘要

以[NH4][C3H5NO4]为原料，以四氟化硫为原料，在无水氟化氢（aHF）中合成了2-氨基丙烯酰二氟化单质子化产物1,3-二氟-1,3-二氧丙烷-2-氨基三氟化二氢[C3H4F2NO2][H2F3]。溶剂被除去，盐在aHF中溶解并结晶。在固体状态下，三维网络由中等强度的N-H…F氢键和C。F联系人。这是二氟化氨基酰基的第一次结构测定和氟化氨基酰基的第二次结构测定。

Monoprotonated species of 2-aminomalonyl difluoride, [C₃H₄F₂NO₂][H₂F₃].

The monoprotonated species of 2-aminomalonyl difluoride, namely, 1,3-difluoro-1,3-dioxopropan-2-aminium dihydrogen trifluoride, [C₃H₄F₂NO₂][H₂F₃], was synthesized from sulfur tetrafluoride in anhydrous hydrogen fluoride (aHF) with [NH₄][C₃H₅NO₄] as the starting material. The solvent was removed and the salt was dissolved in aHF and crystallized. In the solid state, the three-dimensional network is built by medium-strong N-H...F hydrogen bonds and C...F contacts. This is the first structure determination of an aminoacyl difluoride and the second of an aminoacyl fluoride.

期刊介绍： Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
