A Green approach for the synthesis of 2-aminonicotinonitriles from oxime acetate as enamine precursor, aldehyde and malononitrile under neat condition without the use of additive in presence of [email protected]2O3 nanocatalyst is reported. Wide substrate scope, high yield in shorter reaction time, avoid the usage of bases/additives with better green chemistry matrices like low E factor and PMI, high
报道了在纯净条件下在[电子邮件保护的] 2 O 3纳米催化剂存在下不使用添加剂的情况下,由乙酸肟作为烯胺前体,醛和丙二腈合成2-氨基烟腈的绿色方法。与文献方法相比,较宽的底物范围,高收率,更短的反应时间,避免使用具有较低E因子和PMI的绿色化学更好的碱/添加剂,原子经济性,碳效率和反应质量效率高的碱/添加剂。[受电子邮件保护] 2 O 3纳米催化剂被回收并再循环了五次,而其催化活性并未显着降低。
