Abstract:The title compound 5,6-O-(4-chlorophenyl)-L-ascorbic acid (C13H11ClO6) was synthesized using nanosolid superacid SO2-4/SnO2 as a catalyst and its structure was characterized by IR, 1H NMR and single-crystal X-ray diffraction. 1H NMR data indicated the product is a mixture of two diastereomer compounds (a(7S) and b(7R)). And the crystal of one diastereomer compound a(7S) belongs to orthorhombic system, space group P212121 with a = 6.501(4), b = 7.803(5), c = 25.013(15) Å, V 1268.7(13) Å3, Z = 4, Dc 1.564g/cm3, … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
