以一系列芳醛和N4-苯基氨基硫脲为原料,浓盐酸做催化剂,在室温条件下,进行反应合成了5个芳醛缩氨基硫脲类化合物,结果表明,浓盐酸催化下的反应能够在1 h内完成,并且产率在90%左右,是合成该类化合物的高效催化剂。
A series of aromatic aldehydes and N4-phenylthiosemicarbazide as raw materials, concentrated hydrochloric acid as a catalyst at room temperature, the reaction of five synthetic aldehyde thiosemicarbazone compounds, the results show that concentrated hydrochloric acid-catalyzed reaction Can be completed in 1 h, and the yield is about 90%, which is an efficient catalyst for the synthesis of these compounds.
