a Keggin-type heteropolyacids series (H3PW12O40·13H2O; H4SiW12O40·13H2O; H4SiMo12O40·13H2O; and H3PMo12O40·13H2O) as catalysts without solvent and under microwave irradiation. We found that the use of H3PW12O40·13H2O acid coupled to microwave irradiation allowed obtaining a high-yielding reaction with a short time. The compound structures were established by 1H-NMR and 13C-NMR. The antibacterial and
2-苯甲酰氨基-N-苯基-苯甲酰胺衍生物 (5a-h) 由 2-苯基-3,1-(4H)-苯并恶嗪-4-one 3 和取代的苯胺 4a-h 在 Keggin 型存在下制备杂多酸系列(H3PW12O40·13H2O;H4SiW12O40·13H2O;H4SiMo12O40·13H2O;和H3PMo12O40·13H2O)作为催化剂,无溶剂和微波辐射。我们发现使用H3PW12O40·13H2O酸与微波辐射耦合可以在短时间内获得高产率反应。化合物结构由1H-NMR和13C-NMR确定。合成化合物的抗菌和抗真菌活性表现出抑制细菌和真菌的生长。
