Polyaniline, Polyaniline/SiO2 and Poly(4-vinylpyridine): as Highly Efficient and Recyclable Green Heterogeneous Basic Catalysts for the Three-Component Synthesis of Tetrahydrobenzopyran and 3,4-Dihydropyrano[c]Chromene Derivatives

Polyaniline, polyaniline/SiO2, and poly(4-vinylpyridine) are highly effective base catalysts for the synthesis of tetrahydrobenzo[b]pyran and 3,4-dihydropyrano[c]chromene derivatives by the one-pot three-component condensation reaction of aryl aldehydes, malononitrile and α-hydroxy or α-amino activa...

The remarkable advantages of this new procedure are high yields, short experimental time, mild reaction condition, low cost and easy preparation of the catalysts, and no need for any workup and purification after completion of the reaction. In addition, these catalysts exhibited excellent recoverability without a negligible decrease of their activities after at least six cycles of reaction. multi-component reaction, tetrahydrobenzopyrans 3,4-dihydropyrano[c]chromenes green solvent heterogeneous catalyst, ionic liquid Chemical engineering Chemistry Behjat Pouramiri verfasserin aut Mahboobeh Zahedifar verfasserin aut Hassan Sheibani verfasserin aut Kazem Saidi verfasserin aut In Iranian Journal of Chemistry & Chemical Engineering Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2020 40(2021), 2, Seite 429-436 (DE-627)501417176 (DE-600)2206335-3 10219986 nnns volume:40 year:2021 number:2 pages:429-436 https://doi.org/10.30492/ijcce.2020.37864 kostenfrei https://doaj.org/article/5e7d626346ee4c1eae6cf499ec7644d9 kostenfrei http://www.ijcce.ac.ir/article_37864_bfa1c8f7f2304e67f0eec7a03e0333db.pdf kostenfrei https://doaj.org/toc/1021-9986 Journal toc kostenfrei https://doaj.org/toc/1021-9986 Journal toc kostenfrei GBV_USEFLAG_A SYSFLAG_A GBV_DOAJ GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_95 GBV_ILN_105 GBV_ILN_110 GBV_ILN_151 GBV_ILN_161 GBV_ILN_170 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_602 GBV_ILN_2014 GBV_ILN_4012 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4249 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4335 GBV_ILN_4338 GBV_ILN_4367 GBV_ILN_4700 AR 40 2021 2 429-436

abstract	Polyaniline, polyaniline/SiO2, and poly(4-vinylpyridine) are highly effective base catalysts for the synthesis of tetrahydrobenzo[b]pyran and 3,4-dihydropyrano[c]chromene derivatives by the one-pot three-component condensation reaction of aryl aldehydes, malononitrile and α-hydroxy or α-amino activated C–H acids such as 1,3-cyclohexanedione, dimedone, 4-hydroxy-6-methylpyrone, 4-hydroxycoumarin, 1,3-dimethylbarbituric acid, and 1,3-dimethyl-6-amino uracil. The remarkable advantages of this new procedure are high yields, short experimental time, mild reaction condition, low cost and easy preparation of the catalysts, and no need for any workup and purification after completion of the reaction. In addition, these catalysts exhibited excellent recoverability without a negligible decrease of their activities after at least six cycles of reaction.

The remarkable advantages of this new procedure are high yields, short experimental time, mild reaction condition, low cost and easy preparation of the catalysts, and no need for any workup and purification after completion of the reaction. In addition, these catalysts exhibited excellent recoverability without a negligible decrease of their activities after at least six cycles of reaction.</subfield></datafield><datafield tag="650"
