Suzuki cross coupling is one of the ways to make bonds between two carbon atoms of similar molecules or different molecules. C C bond was successfully formed between two aryl rings of aryl halides and phenylboronic acid at room temperature and atmospheric pressure under the visible illuminance. Suzuki Mechanism This video tutorial looks at the Suzuki mechanism one step at a time. Myers The Suzuki Reaction Chem 115 Harvard University Miyaura, N.; Suzuki, A. J. Chem. Soc., Chem. mun. 1979, 866–867. The Suzuki reaction is the coupling of an aryl or vinyl boronic acid with an aryl or vinyl halide or triflate using a palladium catalyst. It is a powerful cross coupling method that allows for the synthesis of conjugated olefins, styrenes, and biphenyls: Akira Suzuki (chemist) Akira Suzuki (鈴木 章, Suzuki Akira, born September 12, 1930) is a Japanese chemist and Nobel Prize Laureate (2010), who first published the Suzuki reaction, the organic reaction of an aryl or vinyl boronic acid with an aryl or vinyl halide catalyzed by a palladium(0) complex, in 1979. Suzuki Cross Coupling Reaction A Review Application of Suzuki cross coupling reaction in natural product synthesis 1) The first ever application of suzuki cross coupling reaction in natural products synthesis was reported in the year 1981 by Rossi and his coworkers in which an insect pheromone isolated from Diparopsis castanea has been synthesized (11) 스즈키·미야우라 반응 위키백과, 우리 모두의 백과사전 스즈키·미야우라 반응(일본어: 鈴木・宮浦反応) 또는 스즈키·미야우라 커플링(일본어: 鈴木・宮浦カップリング, 영어: Suzuki Miyaura coupling)은 팔라듐 촉매와 염기 등의 친핵체 작용에 의해 유기붕소화합물과 할로겐화아릴을 커플링 반응시켜서 비대칭 비아릴(바이페닐 유도체)을 얻는 화학반응이다.
