Abstract

하기의 구조식 (Ⅱ)의 아릴 알데히드와 구조식(Ⅲ)의 2-시아노아세트산 유도체를 용매에 첨가하여 용해한 후 촉매를 첨가하거나 또는, 상기한 아릴 알데히드와 상기한 2-시아노아세크산 유도체에 촉매를 첨가하고, 상기 촉매가 첨가된 혼합액을 가열하여, 상온 내지 상승된 온도에서 방치한 후, 상기 생성물을 냉각한 후 산성 용액을 첨가하여 pH를 조절하는 공정으로 하기 구조식(Ⅰ)의 3-아릴-2-시아노아크릴산 유도체를 제조한다.A catalyst is added after dissolving an arylaldehyde of the following structural formula (II) and a 2-cyanoacetic acid derivative of the structural formula (III) in a solvent or by adding a catalyst to the arylaldehyde and the 2-cyanoacetic acid derivative Adding an acidic solution to the mixture to adjust the pH of the product after cooling the product after heating the mixed solution to which the catalyst has been added and heating the mixture at a temperature ranging from room temperature to elevated temperature, -2-cyanoacrylic acid derivative.

(상기 식에서, R1은 수소 원자, C1~ C2의 알콕시기로 이루어진 그룹에서 선택되며, R2는 수소원자, C1~ C8의 알킬기로 이루어진 그룹에서 선택된다.)Wherein R 1 is selected from the group consisting of a hydrogen atom, a C 1 to C 2 alkoxy group, and R 2 is selected from the group consisting of a hydrogen atom and a C 1 to C 8 alkyl group.
