A basic ionic liquid, namely 1,1'-(butane-1,4-diyl)bis(1,4-diazabicyclo [2.2.2]octan-1-ium) hydrox-ide, was prepared and characterized using Fourier-transform infrared spectroscopy, XH nuclear magnetic... A basic ionic liquid, namely 1,1'-(butane-1,4-diyl)bis(1,4-diazabicyclo [2.2.2]octan-1-ium) hydrox-ide, was prepared and characterized using Fourier-transform infrared spectroscopy, XH nuclear magnetic resonance spectroscopy, and pH measurements. The ionic liquid was used for efficient promotion of the synthesis of pyrano[2,3-d]pyrimidinone and pyrido[2,3-d]pyrimidine derivatives at room temperature under grinding conditions. A simple procedure, short reaction time, high yields, non-column chromatographic separation, commercial availability of the starting materials, and recyclability of the catalyst are attractive features of this process. 展开更多

Poly(4-vinylpyridinium) perchlorate has been used as an efficient solid acid catalyst for the synthesis of 3,3'-(arylmethylene)bis(4-hydroxycoumarins) and bis(indolyl)methanes, with the products being formed in excellent yields over very short reaction times under mild and environmentally friendly conditions. This catalyst can be reused several times without any appreciable loss in its activity. 展开更多
