SONOGASHIRA COUPLING -- POLYMER -- MONOAZATRIPHENYLENE -- 3,6-DI(THIOPHEN-2- YL)PYRROLO[3,4-C]PYRROLE- 1,4(2H,5H)-DIONE
Аннотация: A new co-polymer based on fragments of 2-(2-pyridyl)monoazatriphenylene and 2,5-bis (2-ethylhexyl)-3,6-di(thiophen-2-yl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione was prepared by using the Sonogashira reaction. The photophysical properties of the polymer were studied. The presence of a strong bathochromic shift of the absorption and emission maxima in comparison with the previously described monomer units is shown. The polymer exhibits an intense “turn-off” response toward Cu2+ cations.

    Iron(III)-catalyzed multicomponent synthesis of highly substituted pyrroles under ball-milling conditions / A. Mukherjee, S. Al-Ghezi Basim, G. V. Zyryanov, O. N. Chupakhin // Современные синтетические методологии для создания лекарственных препаратов и функциональных материалов" (MOSM 2021): V международная конференция: сборник тезисов. - Екатеринбург, 2021. - C. PR-186

Аннотация: Nowadays, green chemistry plays an important role for environment. In this context, development of solvent-free ball milling or a grinding approach has attracted considerable interest in organic synthesis.1 Hence, carrying out a reaction under solvent-free conditions and at room temperature is an effective approach to eliminate the use of volatile organic compounds and to obtain the greenness in the process. On the other hands, pyrroles are the small aromatic, nitrogen-containing heterocyclic compounds present in many natural products.2 Pyrrole molecules show important biological relevance such as porphyrins, bile pigments, and coenzymes and are known to exhibit various applications as organic materials.3 In this work, we have presented a highly robust one-pot, four-component cascade cyclization reaction of α-keto aldehydes, anilines, activated alkynes, and aromatic nucleophiles to synthesize a diverse range of pharmaceutically important penta-substituted pyrroles. The reaction proceeded smoothly under ball-milling conditions in presence of iron catalyst.

    (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.
