A novel and efficient method for the synthesis of arylboronic acid pinacol esters via a palladium- or iron-catalyzed cross-coupling reaction of arylfluorides with bis(pinacolato)diboron (B2pin2) in the presence of LiHMDS was developed. The Pd-catalyzed defluoroborylation of fluoroarenes is compatible with a variety of functional groups such as primary and secondary amine, ketone, trifluoromethyl,
본 발명은 중수소화 방향족 화합물의 신규 제조방법 및 상기 방법에 의해 제조된 중수소화 방향족 화합물에 관한 것이다. 본 발명에서는 산화성이 상대적으로 낮은 설폰산 촉매를 채택하여 최종물의 구조 변성을 방지함과 동시에 상압 하에서 소량의 중수소원을 사용하더라도 높은 중수소 전환율과 제조 수율을 확보할 수 있다.
