    (Mechano)synthesis of azomethine- and terpyridine-linked diketopyrrolopyrrole-based polymers / W. K. A. Al-Ithawi, A. F. Khasanov, M. I. Valieva [et al.] // Chimica Techno Acta. - 2023. - Vol. 10, № 2. - P202310204

DIKETOPYRROLOPYRROLE-BASED POLYMERS -- PD-CATALYZED SYNTHESIS -- MECHANOSYNTHESIS
Аннотация: Three efficient synthetic approaches towards new azomethine- and terpyridine-containing 2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione (diketopyrrolopyrrole, DPP) based polymers, such as P1 and P2, are reported. The first approach involves the Pd-catalyzed synthesis via two- or three-component Suzuki or Stille cross-coupling reaction in solution. The second approach involves Pd-catalyzed Suzuki cross-coupling reaction under ballmilling conditions. And, finally, the third approach involves Pd-free condensation reaction under ball-milling conditions. The newly obtained polymers exhibited absorbance around 700 nm and emission around 900 nm, and, thus, these polymers are considered to be NIR-fluorophores.

BOND ACTIVATION -- INHIBITORS -- HYDROGEN
Аннотация: In this paper we wish to report a highly selective and benign method for the double C-H/C-H coupling of azaaromatics with indoles or pyrrole in the presence of air oxygen/TiO2, as an effective photocatalytic oxidative system. It has been shown that this versatile approach can be applied for direct C-H functionalisation of a variety of azaaromatic systems, such as mono-, di- and triazines, substituted and unsubstituted azines and their benzo-annelated analogues.

SYNTHETIC METHODS -- CROSS-COU­PLING -- NITROGEN HETEROCYCLES
Аннотация: The combination of the Suzuki–Miyaura cross-coupling and nucleophilic aromatic substitution of hydrogen reactions is a versatile tool for the syntheses of 4-(1R-pyrrol-2-yl)- and 4-(1R-indol-3-yl)-5-(hetero)aryl-substituted pyrimidines from commercially available 5-bromopyrimidine. The SNH [AE, (addition–elimination)] and SNH [AO, (addition–oxidation)] reactions of 5-bromopyrimidine with pyrroles and indoles were studied by gas chromatography–mass spectrometry. The structures of the intermediate σH adducts as well as the pyrrole-(hetero)arylpyrimidine and indole-(hetero)arylpyrimidine dyads were established for the first time by X-ray crystal structure analysis

FUSED THIOPHENE -- PYRROLE RINGS -- FISCHER INDOLIZATION REACTION
Аннотация: A convenient approach to ladder-type 6H-benzo[4',5']thieno[2',3':4,5]thieno[3,2-b]indoles, e.g., I (X-rays single crystal structure shown)​, bearing various substituents in both terminal benzene rings has been developed. The protocol suggested for prepg. these N,S-​heteroacenes is based on using easily available reagents, such as cinnamic acids and arylhydrazines, which can be involved in the Fischer indole synthesis, as the key step. A similar condensed system of 12H-​benzo[4'',​5'']​thieno[2'',3'':4',5']​thieno[2',3':4,5]​thieno[3,2-b]indole, bearing six rings, has also been obtained.
