The scheme above shows the first published Suzuki Coupling, which is the palladium-catalysed cross coupling between organoboronic acid and suzuki miyaura. Recent catalyst and methods developments have broadened the possible applications enormously, so that the scope of the reaction partners is not restricted to aryls, suzuki miyaura, but includes alkyls, alkenyls and alkynyls. Potassium trifluoroborates and organoboranes or boronate esters may be used in place of boronic acids.

The palladium-catalysed Suzuki—Miyaura cross-coupling reaction of organohalides and organoborons is a reliable method for carbon—carbon bond formation. This reaction involves a base-mediated transmetalation process, but the presence of a base also promotes competitive protodeborylation. Herein, we established a Suzuki—Miyaura cross-coupling reaction via Lewis acid-mediated transmetalation of an organopalladium II intermediate with organoborons.

Suzuki-Miyaura coupling or Suzuki coupling is a metal catalyzed reaction, typically with Pd, between an alkenyl vinyl , aryl, or alkynyl organoborane boronic acid or boronic ester, or special cases with aryl trifluoroborane and halide or triflate under basic conditions. This reaction is used to create carbon-carbon bonds to produce conjugated systems of alkenes, styrenes, or biaryl compounds Scheme 1. Scheme 1: General reaction scheme of Suzuki cross coupling reaction. Chemler, S. The Suzuki coupling is a pioneering reaction in cross coupling, and has been thoroughly studied since. The first Suzuki-type cross coupling reaction between phenylboronic acid and haloarenes was published by Suzuki and Miyaura in Scheme 1. Both couplings have a similar reaction scope and proceed via a similar mechanistic cycle. Scheme 1: Suzuki cross coupling reaction of phenylboronic acid and haloarenes. Stille cross coupling reactions can form carbon-carbon bonds between alkenyl vinyl , aryl, or alkynyl halides and an extended scope of organotin alkynes, alkenes, aryl, allyl benzyl, ketones, and alkyl. However, Stille coupling poses several drawbacks seeing that organotin reagents are: 1 highly toxic, 2 costly, and have a 3 lower functional group tolerance, despite Suzuki coupling not being suitable for base sensitive substrates.

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. Heck and Ei-ichi Negishi for their contribution to the discovery and development of noble metal catalysis in organic synthesis. It is widely used to synthesize poly olefins , styrenes , and substituted biphenyls. The general scheme for the Suzuki reaction is shown below, where a carbon-carbon single bond is formed by coupling a halide R 1 -X with an organoboron species R 2 -BY 2 using a palladium catalyst and a base. The organoboron species is usually synthesized by hydroboration or carboboration , allowing for rapid generation of molecular complexity. Several reviews have been published describing advancements and the development of the Suzuki reaction. The mechanism of the Suzuki reaction is best viewed from the perspective of the palladium catalyst.

The ever-increasing interest in the Suzuki—Miyaura cross-coupling reaction SMR and its applications, with more than 40 years of history, has increased exponentially in the last decade, which speaks volumes about its efficiency and effectiveness. This widely used powerful method provides a practical synthetic route for the direct formation of carbon—carbon bonds, which has found considerable academic and industrial use for the production of polymers, fine chemicals and materials, in addition to total synthesis and pharmaceuticals. Green chemistry predicates the use of environmentally-benign media in organic transformations and in recent years, catalytic systems have been introduced in diverse and neoteric green media for SMR. In view of the widespread popularity, there is the need for a comprehensive understanding of the various greener strategies introduced for this important reaction encompassing diverse catalytic systems based on palladium, nickel, gold, ferrites, copper, silver, and cobalt. The present review embodies literature from onward that covers the SMR using efficient catalysts in various green media. Hooshmand, B. Heidari, R.

Kim, P. In the case of the Suzuki coupling the ligands are transferred from the organoboron species D to the palladium II complex C where the base that was added in the prior step is exchanged with the R 2 substituent on the organoboron species to give the new palladium II complex E. Lassaletta, J. Supplementary Data 1 Crystallographic data for compound 4. Scheme 2: Suzuki cross coupling reaction application: Epothilone total synthesis. Ruthenium is another metal source that has been used in Suzuki coupling reaction. Han, F. Figure 1: Representative monodentate phosphine ligands. Sheng, C. Darses, S. Replacements for halides were also found, increasing the number of coupling partners for the halide or pseudohalide as well. Lehmann, F. The observed formation of a zinc hydroxide oligomer as an insoluble by-product further supported our argument Supplementary Fig.

Being able to use water as a solvent [19] makes this reaction more economical, eco-friendly, and practical to use with a variety of water-soluble reagents. However, reversing the order in which the reagents are added yields the anti addition product, which is also reflected in reductive elimination. Transmetallation and reductive elimination both retains the regio- and stereochemistry established in oxidative addition. Castanet, F. Ferraro, D.
