Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 16251-45-9, Name is (4S,5R)-4-Methyl-5-phenyloxazolidin-2-one. In a document, author is Bouayad, Kaoutar, introducing its new discovery. COA of Formula: C10H11NO2.
Crystal structure of 5-chloro-1,3-bis[2-(2oxo-1,3-oxazolidin-3-yl)ethyl]-1H-benz-imidazol-2(3H)-one
In the title compound, C17H19ClN4O5, the benzimidazole fused -ring system is essentially planar, the maximum deviation from the mean plane being 0.06 (1) angstrom. Both oxazolidine rings are nearly planar, the maximum deviations from the mean planes are 0.071 (13) and 0.070 (10) angstrom. The dihedral angle between the mean planes of the oxazolidine rings is 69.9 (7). The benzimidazole mean plane makes the dihedral angles of 43.9 (6) and 45.6 (6)degrees with the two oxazolidine rings. In the crystal, the molecules are linked together by weak C-H center dot center dot center dot O hydrogen bonds building zigzag tapes running along the c axis. The Cl atom is split over two positions with an occupancy ratio of 0.567 (7):0.433 (7). This means that the reaction yields two isomers, A and B; the A component has the Cl-atom substituent in the 5-position of the benzimidazolone ring and the B component has the Cl atom in the 6 -position. The two isomers form the disordered co-crystal, with a nearly half Cl atom in each of them, as indicated by the occupancy ratio. The crystal structure was refined as an inversion twin.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 16251-45-9 help many people in the next few years. COA of Formula: C10H11NO2.
