The Suzuki reaction or Suzuki coupling is an organic reaction that uses a palladium complex catalyst to cross-couple a boronic acid to an organohalide. [1] [2] [3] It was first published in 1979 by Akira Suzuki, and he shared the 2010 Nobel Prize in Chemistry with Richard F. Heck and Ei-ichi Negishi for their contribution to the discovery and development of noble metal catalysis in organic ...
Norio Miyaura (宮浦憲夫, Miyaura Norio) was a Japanese organic chemist. He was a professor of graduate chemical engineering at Hokkaido University. [1] His major accomplishments surrounded his work in cross-coupling reactions / conjugate addition reactions of organoboronic acids (for C-C bond-forming reactions) and addition / coupling reactions of diborons and boranes (to synthesize ...
The Miyaura borylation has shown to work for: Alkyl halides, [ 2 ] aryl halides, [ 1 ] [ 3 ] [ 4 ] aryl halides using tetrahydroxydiboron , [ 5 ] aryl halides using bis-boronic acid, [ 6 ] aryl triflates , [ 7 ] aryl mesylates , [ 8 ] vinyl halides, [ 9 ] vinyl halides of α,β-unsaturated carbonyl compounds, [ 10 ] and vinyl triflates.
Typically the electrophilic coupling partner (R-X) is an aryl halide, but triflates are also used. Nucleophilic coupling (R'-Y) partners are more diverse. In the Suzuki reaction, boronic esters and boronic acids serve as nucleophilic coupling partners. [1] Expanding the scope of coupling partners is a focus methods development in organic ...
Being a center for trade in the Indian Ocean since antiquity, however, the history of collection of customs duties in Sri Lanka dates far back as the second century BC. [citation needed] "According to the inscription of King Gajaba I (112-134 A.D.) the customs duty collected from the Godapavata Harbour had been donated to the Godapavata monastery.
