1 Source of material
To a 50 mL round bottom flask, add 2-chloroselenylbenzoyl chloride (0.5 mmoL) and 3 mL acetone and the mixture was kept for 18 h under anhydrous condition at room temperature. After the reactant completely reacts, o–phenylenediamine (0.5 mmoL) is added and the reaction continues for 15 min. Add 5 mL water slowly to quench the reaction, and let it stand to precipitate crystals. For the crude product without crystal precipitation, use ethyl acetate Ester (3 × 20 mL) extraction, column chromatography (petroleum ether/ethyl acetate = 3:1) separation and purification to obtain the target product.
2 Experimental details
Using Olex2 [2], the structure was solved with the ShelXS [3] structure solution program and refined with the ShelXL [4] refinement package.
3 Comment
As an organic selenium compound with antioxidant and anti-inflammatory properties, Ebselen is a mimic of glutathione peroxidase (GPX) and an excellent scavenger of peroxynitrite [5]. The crystals that it combines with various organic amino acids have attracted much attention [6, 7] and its analogues were extensively studied [8, 9]. The title crystal is symmetric Ebselen analogue of open loop mother nucleus, it is the latest discovery based on previous research [10]. The crystal structure is shown in the Figure which includes that the two open loop mother nucleus of Ebselen are connected to acetone by Se–C and they are connected to the ortho benzene ring. The dihedral angles between the C8–C9–C10 plane and other two benzene planes where the C1–C2–C3 and C15–C16–C17 are located were found to be
