A series of N-heteroaryl formamides were efficiently synthesized from heteroarylamines and formic acid using Al2O3 nanoparticles as a heterogeneous catalyst under solvent-free conditions. The smaller size of Al2O3 nanoparticles with a higher surface to volume ratio has a promising catalytic activity, resulting in a short reaction times and high reaction yields under mild reaction conditions. The catalyst could be recycled and reused four times without a noticeable decrease in its activity.
以Al2O3纳米颗粒为多相催化剂，在无溶剂条件下，由杂芳胺和甲酸高效合成了一系列N-杂芳基甲酰胺。具有较高表面体积比的较小尺寸Al2O3纳米颗粒具有良好的催化活性，在温和的反应条件下反应时间短、产率高。该催化剂可循环使用四次，其活性无明显下降。
