- Method for preparing (E)-2-aryl-alpha, beta-unsaturated carbonyl phosphonate derivative
-
The invention discloses a method for preparing a (E)-2-aryl-alpha, beta-unsaturated carbonyl phosphonate derivative (I) (please the formula in the description), and belongs to the field of organic chemistry. According to the method, a 2-aryl-alpha, beta-unsaturated carbonyl compound and phosphite ester serve as raw materials and react with tetrahydrofuran (THF) and other materials as a solvent under the combined action of AgNO3 catalyzing and an assistant agent at the temperature of 20-80 DEG C, and then the (E)-2-aryl-alpha, beta-unsaturated carbonyl phosphonate derivative is obtained. According to the method, the 2-aryl-alpha, beta-unsaturated carbonyl compound serves as the initial raw material, the raw materials are low in price and easy to obtain, reaction conditions are mild, operation is easy and convenient, the synthesis yield is high, and industrial production is facilitated. The derivative has potential application in chemical engineering, medicine, cosmetics and other fields, and a new approach is provided for synthesis of the (E)-2-aryl-alpha, beta-unsaturated carbonyl phosphonate derivative.
