Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials. , Application of 83846-85-9, 83846-85-9, Name is Phenyl(4-(p-tolylthio)phenyl)methanone, molecular formula is C20H16OS, belongs to thiomorpholine compound. In a document, author is Mawad, Nasser, introduce the new discover.
The synthesis of 3,3-dimethylmorpholine-2,5-diones 4a was achieved conveniently via the ‘direct amide cyclization’ of the linear precursors of type 3, which were prepared by coupling of 2,2-dimethyl-2H-azirin-3-amines 2 with 2-hydroxyalkanoic acids 1. Thionation of 4a with Lawesson’s reagent yielded the corresponding 5-thioxomorpholin-2-ones 10 and morpholine-2,5-dithiones 11, respectively, depending on the reaction conditions. The structures of 3aa, 4aa, 10a, and 11a were established by X-ray crystallography. All attempts to prepare S-containing morpholine-2,5-dione analogs or thiomorpholine-2,5-diones by cyclization of corresponding S-containing precursors were unsuccessful and led to various other products. The structures of some of them have also been established by X-ray crystallography.
