Di-tert-butyl 3,6-bis(2-methylphenyl)-1,4-dioxo-1,2,4,5-tetrahydropyrrolo[3,4-c]pyrrole-2,5-dicarboxylate

Abstract

The title compound, C30H32N2O6, is a soluble precursor (`latent pigment') of diketopyrrolo­pyrrole pigments. The mol­ecule has inversion symmetry. The aryl ring and tert-butoxy­carbonyl group are twisted with respect to the heterocyclic ring by 64.5 (1) and 30.7 (1)°, respectively.
