- Synthetic studies related to diketopyrrolopyrrole (DPP) pigments. Part 3: Syntheses of tri- and tetra-aryl DPPs
-
Novel synthetic methodologies leading towards 2,3,5-triaryl- and 2,3,5,6-tetraaryl-2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-diones (tri- and tetra-aryl-DPPs) and their derivatives have been investigated. Direct arylation of 3,6-diphenyl-DPP was possible using
