✦ Synopsis

H -Diiodobiphenyl, C 12 H 8 I 2 , crystallizes as a homologous isomorph of the high-temperature form of p-diiodobenzene. The molecule is planar and lies on a center of symmetry. Each I atom is in contact with ®ve others at distances between 4.0 and 4.5 A Ê .

The title compound, C 12 H 8 I 2 N 2 O, was obtained as an unexpected product while attempting to protect N,N-dibutyl-4-iodoaniline as the N-oxide. It crystallizes as a layer structure. Oxidation of (II) by hydrogen peroxide gives the N-oxide (III). This eliminates butene via a Cope reaction (Adams

The title compound, C 32 H 23 Cl 2 N, was synthesized via the Ullmann reaction. The orientations of the three aromatic rings attached to the vinyl group are determined by the sp 2 state of the vinyl C atoms. The crystal packing is stabilized by weak CÐHÁ Á Á% interactions.
