The title compound, C 16 H 10 N 4 O 2 , is an organic red pigment utilized for hydrogen gas sensors. The centrosymmetric diketopyrrolopyrrole is nearly planar and is linked to four neighbouring molecules via N-HΓ Γ ΓN hydrogen bonds to form a two-dimensional network in the (201) plane.
The title compound, C 23 H 25 BrO 3 , was synthesized by the reaction of p-bromobenzaldehyde with dimedone and HClO 4 / SiO 2 in EtOH. In the molecule, the dihydropyran ring adopts a boat conformation and the two cyclohexene rings are in a trans conformation.
