When using a catalyst represented by chemical formula 1 according to the present invention in manufacturing an organic fluorinated compound by conducting a reaction of alkyl halide or alkyl sulfonate, potassium fluoride or cesium fluoride, which is a fluoride salt, an alkali positive ion is combined with a crown ether group and a fluorine negative ion is hydrogen-bonded with a hydroxy group to weaken ionic bonds of alkali metal fluoride to promote a fluorination reaction, and also to have an effect of significantly inhibiting the production of by-product alkenes. 본 발명에 따른 화학식 1로 표시되는 촉매를, 알킬 할라이드 또는 알킬 술폰네이트와; 플루오라이드 염인 포타슘 플로라이드 또는 세슘 플로라이드와 반응시켜 유기 플루오르화 화합물을 제조하는 방법에 사용할 경우, 알칼리 양이온이 크라운 에테르 단과 결합하고, 플루오린 음이온이 하이드록시 단과 수소결합을 하여 알칼리 금속 플로라이드의 이온성 결합을 약화시켜 플루오르화 반응을 촉진할 뿐만 아니라, 부생성물인 알켄의 생성이 현저히 억제되는 효과가 있다.
