Suzuki reaktion
The Suzuki reaction is an organic reaction, classified as a cross-coupling reaction, where the coupling partners are a boronic acid and an organohalide and the catalyst is a palladium(0) complex. It was first published in 1979 by Akira Suzuki, and he shared the 2010 Nobel Prize in Chemistry with Richard F. … Visualizza altro The mechanism of the Suzuki reaction is best viewed from the perspective of the palladium catalyst. The catalytic cycle is initiated by the formation of an active Pd catyltic species, A. This participates in the oxidative addition Visualizza altro Industrial applications The Suzuki coupling reaction is scalable and cost-effective for use in the synthesis of intermediates for pharmaceuticals or fine chemicals. … Visualizza altro • Chan-Lam coupling • Heck reaction • Hiyama coupling • Kumada coupling Visualizza altro The advantages of Suzuki coupling over other similar reactions include availability of common boronic acids, mild reaction conditions, and its less toxic nature. Boronic acids are less toxic and safer for the environment than organotin and organozinc compounds Visualizza altro Metal catalyst Various catalytic uses of metals other than palladium (especially nickel) have been developed.
