采用氰杂络合物前驱体分解法（CN法）制备了钙钛矿型氧化物催化剂SmFeO 3，并将其应用于苯甲醛与TMSCN的硅腈化反应。CN法在800 °C焙烧温度下催化剂的活性最高，催化剂的活性与SmFeO 3的结晶度密切相关。在吡啶和2，6-二叔丁基吡啶存在下进行的催化反应表明，SmFeO 3催化剂上形成的Brønsted酸中心是催化活性中心. CN法制备的SmFeO 3催化剂的催化活性远高于酸性催化剂SiO2-Al 2 O3和Amberlyst。
The perovskite-type oxide catalyst, SmFeO3, prepared by decomposition method of heteronuclear cyano complex precursor (CN method) was applied to liquid-phase organic reaction, cyanosilylation of benzaldehyde with TMSCN. The maximum catalytic activity per catalyst weight was achieved at 800 °C of calcination temperature in CN method and it was found that the catalytic activity was strongly related to the crystallinity of SmFeO3catalyst. The catalytic reaction performed in the presence of pyridine and 2,6-di-tert-butylpyridine suggests that the catalytically active sites are the Brønsted acid sites formed on the SmFeO3catalyst. The catalytic activity of SmFeO3catalyst prepared by CN method was much higher than those of acid catalysts: SiO2–Al2O3and Amberlyst.
