8-Bromo-1,3-diphenyl-2,3-dihydro-1H-naphtho[1,2-e][1,3]oxazine

Abstract

The title compound, C24H18BrNO, consists of an envelope-configured oxazine ring with a fused 8-bromo-1,3-diphenyl group and two bonded phenyl rings. The dihedral angles between the mean planes of the 8-bromo-1,3-diphenyl and the phenyl rings are 54.5 (6) and 87.4 (8)°, respectively. The oxazine is essentially coplanar with the 8-bromo-1,3-diphenyl [dihedral angle = 9.4 (1)°]. Weak C—H...π interactions contribute to the crystal packing
