They all use palladium as a catalyst in one step of the reaction.
What do the Suzuki reaction, the Heck reaction, and the organocuprate reaction all have in common when they react with an alkyl halide?Īll reactions form new carbon-carbon bonds. Reductive elimination of R-R, forming the new C-C bond Transfer of the alkyl group from the organoborane to palladium Substitution of the R group to the palladium catalyst Oxidative addition of R-X to the palladium catalyst Which of the following is not a step in the Suzuki reaction? The Suzuki reaction involves an oxidative addition followed by a reductive elimination. The Suzuki reaction forms more highly substituted alkenes. The Suzuki reaction involves both an organoborane reagent and an organopalladium catalyst. The product of the Suzuki reaction is completely stereospecific. Which of the reactions listed below is not stereospecific?Ĭhoose the statement below that is not true about the Suzuki reaction. Identify the products of the following reaction. What is the missing reactant in the following reaction? What is the major organic product of the following reaction? The reaction will only yield one enantiomeric product with S configuration. The reaction will only yield one enantiomeric product with R configuration. The reaction will only yield a cis-alkene. The reaction will only yield a trans-alkene. Which choice below best describes the expected product when trans-1-bromo-1-hexene reacts with (CH 3) 2CuLi? The reaction of a vinyl halide with the R 2CuLi reagent will only yield one enantiomer product-either R or S configuration.Ĭoupling reactions with vinyl halides are stereospecific. The reaction of a vinyl halide with the R 2CuLi reagent will only yield the trans product. The reaction of a vinyl halide with the R 2CuLi reagent will only yield the cis product. The reaction of a specific stereoisomer with the R 2CuLi reagent will yield that particular stereoisomer as the product. Which statement below best explains what is meant by the statement, “An organocuprate reaction with a vinyl halide is stereospecific”? Which class of compounds listed below does not react with organocuprate reagents to form a coupling product that contains a new carbon-carbon bond?Ī) 1° alkyl halides B) 3° alkyl halides C) vinyl halides D) aryl halides Which listed reaction is not correct?Īcid chlorides react with organocuprate reagents to form ketones.Įpoxides react with organocuprate reagents to form alcohols.Īlkyl halides react with organocuprate reagents to form coupling products containing a new carbon-carbon bond.Ĭarbon dioxide reacts with organocuprate reagents to form carboxylic acids. Organocuprate reagents (R 2CuLi) react with several compounds. If You Face Any Problem E- Mail Us At 26: Carbon-Carbon Bond Forming Reactions in Organic Synthesis
