| Abstract: The crystalline material (MV)2[HPWⅤ2WⅥ10O40]·2H2O achieved from 1,1′-dimethyl 4,4′-bipyridine (methyl viologen, MV) dichloride and Keggin-type polyoxometalate unit, was used as a highly efficient catalyst for the synthesis of β-amino alcohols under organic solvent-free and room temperature conditions. Experimental results showed that the catalyst could efficiently accelerate the synthesis of β-amino alcohols while maintaining its stability. It could be reused six times and there was no significant decrease in its catalytic activity, indicating its certain recyclability. Compared with traditional synthetic methods, this system demonstrated its advantages in organic solventfree, mild experimental conditions, simple procedures, and environmentally friendly conditions. | |
