Sulfonic acid-functionalized MIL-101(Cr) was established to be an active heterogeneous catalyst for the one-pot synthesis of 2-amino-4H-chromenes via a three-component condensation reaction between resorcinol, malononitrile and a diverse range of aromatic aldehydes in aqueous medium. Here, sulfonation of the parent MIL-101(Cr) has been carried out through a post synthetic modification (PSM) technique
磺酸官能化的MIL-101(Cr)被确立为一种活性多相催化剂,可通过
间苯二酚,
丙二腈和各种芳族化合物之间的三组分缩合反应一锅合成2-
氨基-4 H-色烯。
水性介质中的醛。在此,母体MIL-101(Cr)的磺化已通过合成后修饰(PSM)技术进行。所得的MIL-101(Cr)–SO 3 H通过粉末X射线衍射,N 2吸附,FE
SEM,EDS,FT-IR和TGA研究进行了表征。此外,该催化剂可以容易地回收和再循环,而催化活性没有太大变化。
