2024年10月21日 · SOF 4 (sulfur tetrafluoride) has one sulfur atom, one oxygen atom, and four fluorine atoms. In SOF 4 Lewis structure, there is one double bond and four single bonds around the sulfur atom, with one oxygen atom and four fluorine atoms attached to it. Each fluorine atom has three lone pairs, and the oxygen atom has two lone pairs.

2023年8月15日 · 六价硫氟化物具有高化学稳定性，但在特定活化的条件下又能高效地实现其化学键转化和链接。基于SVI–F键独特的性质，Sharpless与董佳家等人于2014年携手开发了新一代的点击化学—六价硫氟交换（SuFEx, 图1a）。 不同于第一代铜催化的叠氮—炔烃环加成（CuAAC），SuFEx可在无金属条件下进行，这对生物化学的应用至关重要；而且链接形式灵活多样，可允许不同类型的SuFEx链接子与亲核试剂偶联实现高价硫化合物库的构筑。 自那以 …

A gaseous electron‐diffraction investigation of SOF 4 has led to the discovery of four models in excellent agreement with experiment, all with molecular symmetry C 2υ corresponding to replacement of an equatorial fluorine atom of a trigonal bipyramid with oxygen.

We can use the VSEPR model to predict the geometry of most polyatomic molecules and ions by focusing only on the number of electron pairs around the central atom, ignoring all other valence electrons present.

2024年10月1日 · Due to our deep interest in the OSF x (x =4, 5) chemistry, we herein report a safe and selective large-scale preparation of thionyl tetrafluoride to improve the reported procedure.
