promising approach, heterogeneous g-C3N4 as a solid base catalyst exhibits appreciable activity in Knoevenagel condensations at room temperature for the synthesis of substituted stilbene in presence of a crown-ether phasetransfer catalyst. High yield of the product substituted stilbene were isolated in a very short reaction time period (∼30 min). The solid base g-C3N4 catalyst was proven to be recyclable
在一种有前途的方法中,作为固体碱催化剂的多相gC 3 N 4在室温下的Knoevenagel缩合中显示出明显的活性,用于在冠醚相转移催化剂存在下合成取代的苯乙烯。在很短的反应时间(约30分钟)内分离出高产率的取代苯乙烯的产物。固态碱gC 3 N 4催化剂经证实可循环使用多次。使用多相碱式gC 3 N 4催化剂筛选了各种芳族底物,在室温下显示出可观的相应产物收率(〜99%)。
