Silica tungstic acid (STA) has been found to be an efficient and reusable solid acid catalyst for the synthesis of 2-amino-4H-chromenes via the three-component reaction of aromatic aldehydes, malononitrile, and β-naphthol. STA as a novel solid acid was characterized by X-ray fluorescence, X-ray diffraction, and Fourier transform infrared spectroscopy.
已发现硅钨酸（STA）是一种高效且可重复使用的固体酸催化剂，可通过芳香醛、丙二腈和β-萘酚的三组分反应合成2-氨基-4H-色烯。STA作为一种新型固体酸，通过X射线荧光、X射线衍射和傅里叶变换红外光谱进行了表征。
