I found the field of Chemistry very interesting. Saw the article Air-stable binuclear Titanium(IV) salophen perfluorobutanesulfonate with zinc power catalytic system and its application to C-S and C-Se bond formation published in 2020. COA of Formula: C14H10O3, Reprint Addresses Wei, JC; Li, NB (corresponding author), Shanxi Med Univ, Basic Med Coll, Taiyuan 030001, Peoples R China.; Xu, XH (corresponding author), Hunan Univ, Coll Chem & Chem Engn, Changsha 410082, Hunan, Peoples R China.. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride
An air-stable mu-oxo-bridged binuclear Lewis acid of titanium(IV) salophen perfluorobutanesulfonate [{Ti(salophen)H2O)(2)O][OSO2C4F9](2) (1) was successfully synthesized by the reaction of Ti-IV(salophen)Cl-2 with AgOSO2C4F9 and characterized by techniques such as IR, NMR and HRMS. This complex was stable open to air over a year, and exhibited good thermal stability and high solubility in polar organic solvents. The complex also had relatively strong acidity with a strength of 0.8 < Ho <= 3.3, and showed high catalytic efficiency towards various C-S and C-Se bond formations in the presence of zinc power. This catalytic system affords a mild and efficient approach to synthesis of thio- and selenoesters, alpha-arylthio- and seleno-carbonyl compounds, and thio- and selenoethers. (C) 2019 Elsevier Ltd.
