inorganic–organic nanohybrid material SBA-15@triazine/H5PW10V2O40 (SBA-15@ADMPT/H5PW10V2O40) was prepared and used as an efficient, eco-friendly, and highly recyclable catalyst for the one-pot multicomponent synthesis of multisubstituted pyridines from the reaction of aldehydes, cyclic ketones, malononitrile, and ammonium acetate with good to excellent yields (77–97%). The nanohybrid catalyst was prepared by the chemical
一种新颖的无机-有机纳米杂化材料SBA-15 @三嗪/ H 5 PW 10 V 2 ö 40(SBA-15 @ ADMPT / H 5 PW 10 V 2 ö 40)制备并用作有效的,环境友好的,并一种高度可回收的催化剂,用于醛,环酮,丙二腈和乙酸铵的反应,可一锅多组分合成多取代的吡啶,产率好至极好(77-97%)。通过Keggin杂多酸H 5 PW 10 V 2 O 40的化学锚固来制备纳米杂化催化剂。用2-APTS -4,6-双(3,5-二甲基-1H-吡唑-1-基)-1,3,5-三嗪(ADMPT)接头修饰的SBA-15中孔二氧化硅表面上。FT-IR,XRD,SEM,TEM,BET,EDX和DTA-TGA光谱等标准表征数据证实杂多酸H 5 PW 10 V 2 O 40在固定在用ADMPT改性的SBA-15中孔二氧化硅上之后,其完全分散在固体载体的表面上并且保留了其结构。此外,纳米催化剂可
