In the present study, nanocrystalline mixed metal oxide, $CuMnO_3$ catalyst have been synthesized by mechanochemical method with green chemistry approach. The synthesized catalyst was characterized by analytical techniques including FTIR, XRD, SEM, TEM and BET surface area. The synthesized catalyst shows high surface area is $121.06m^2/g$ with particle size 18 nm. The one pot four component synthesis of substituted 2-phenyl-4(3H) quinazolinone from the reaction of anthranilic acid, benzoyl chloride, hydrazine hydrate and substituted benzaldehyde in presence of $CuMnO_3$ nanocatalyst has been carried out. It affords the corresponding products with high yield (76-95%) in very short reaction time. All the obtained products were characterized with $^1HNMR$, $^13}CNMR$, FTIR and EIMS.
本研究采用绿色化学方法,通过机械化学法合成了纳米晶混合金属氧化物 $CuMnO_3$ 催化剂。傅立叶变换红外光谱、XRD、扫描电镜、TEM 和 BET 表面积等分析技术对合成催化剂进行了表征。合成催化剂的比表面积高达 $121.06m^2/g$,粒径为 18 nm。在 $CuMnO_3$ 纳米催化剂存在下,由蚁酸、苯甲酰氯、水合肼和取代的苯甲醛反应生成取代的 2-苯基-4(3H) 喹唑啉酮,并进行了一锅四组分合成。在很短的反应时间内,就能得到相应的高产率产品(76-95%)。所有得到的产物都用 $^1HNMR$, $^13}CNMR$, FTIR 和 EIMS 进行了表征。
