5-(4-Bromo-anilinomethyl-ene)-2,2-dimethyl-1,3-dioxane-4,6-dione
Abstract:
In the title compound, C(13)H(12)BrNO(4), the dihedral angles between the amino-methyl-ene group and the dioxane ring and between the benzyl ring and the amino-methyl-ene unit are 7.96 (4) and 12.15 (4)°, respectively. The dioxane ring shows a half-boat conformation, in which the C atom between the dioxane ring O atoms is 0.460 (8) Å out of the plane through the remaining ring atoms. An intra-molecular N-H⋯O hydrogen bond may stabilize the planar conformation of the mol-ecule. An inter-molecular C-H⋯O inter-action is also present.

Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
