    摘要:
    污染控制需求是设计和开发新反应介质以实现高效率的灵感来源。对环境良性合成的发展给予了极大的关注,包括使用无溶剂条件 1 和应用离子液体 2 或水等溶剂。 3 这些协议已成功用于实现各种化学转化,但仍有一些缺点限制了这些程序的使用。例如,在许多有机反应中,溶剂在促进更有效的分子相互作用方面起着关键作用,但大多数有机化合物不溶于水。此外,由于许多催化剂对水性条件的敏感性,水作为溶剂的使用仅限于一些特殊反应。离子液体也需要繁琐的制备,其环境安全性仍有争议。最近,液体聚合物或低熔点聚合物已成为替代绿色反应介质,具有独特的性质,例如热稳定性、商业可用性、非挥发性、与多种有机溶剂不混溶和可回收性。 4-14 聚(乙二醇) s (PEG) 优于其他聚合物,因为它们价格低廉、完全非卤化、易于降解且毒性低。 4,5 其中,低分子量液体 PEG 可被视为含有非质子位点的质子溶剂。 6 几种有机转化,如 Heck

    In this work, a green, simple and highly efficient procedure for the synthesis of bis(indolyl)methanes and 4,4'-(arylmethylene)-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol)s [as an important class of bis(pyrazolyl) methanes] is described. The condensation of indoles or 1-phenyl-3-methylpyrazol-5-one with carbonyl compounds catalyzed by poly(ethylene glycol)-bound sulfonic acid (PEG-SO3H) in water affords the title compounds in high yields and relatively short reaction times.

    In this work, novel ionic liquid 1-sulfopyridinium chloride [Pyridine-SO3H]Cl} is synthesized, and characterized by IR, H-1 and C-13 NMR, UV as well as mass spectra. The ionic liquid is used as an efficient, homogeneous and reusable catalyst for the synthesis of 4,4'-(arylmethylene)-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol)s by tandem Knoevenagel-Michael reaction of 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one with various aromatic and hetero-aromatic aldehydes under mild reaction conditions.
