5-[(2-Chloro-4-nitro-anilino)methyl-idene]-2,2-dimethyl-1,3-dioxane-4,6-dione
Abstract:
In the title compound, C(13)H(11)ClN(2)O(6), the dihedral angles between the benzene ring and the amino-methyl-ene unit and between the amino-methyl-ene group and the dioxane ring are 8.19 (14) and 1.39 (17)°, respectively. The dioxane ring has a half-boat conformation, in which the C atom between the dioxane O atoms is 0.662 (4)Å out of the plane through the remaining ring atoms. Intra-molecular N-H⋯O and N-H⋯Cl inter-actions occur.

Oxidation of Alkenes: Anti Dihydroxylation with Peroxy Acids
Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
