the fluorescent carbon dots as an effective and recyclable carbocatalyst for the generation of carbon–heteroatom bond leading to quinazolinone derivatives and aza-Michael adducts under mild reaction conditions. The results establish this nanoscale form of carbon as an alternative carbocatalyst for important acid catalyzed organic transformations. The mild surface acidity of carbon dots imparted by
本文中,我们报道了荧光碳点是有效且可回收的碳催化剂,可在温和的反应条件下生成碳-杂原子键,从而导致喹唑啉酮衍生物和氮杂-迈克尔加合物。结果确定了这种碳的纳米级形式,可作为重要的酸催化的有机转化的替代碳催化剂。在当前反应条件下,-COOH官能团赋予的碳点温和的表面酸性可以有效催化合成挑战性的螺/糖基喹唑啉酮的形成。
