Question
Like Hauser bases, solutions of these compounds display the Schlenk equilibrium, so these compounds are typically dissolved in diethyl ether or THF; using dioxane shifts the equilibrium to the other side, destroying them. For 10 points each:
[10e] Name these reagents often used to form carbon-carbon bonds, which are strongly nucleophilic and consist of a halogen and an organic group both bonded to a magnesium.
ANSWER: Grignard reagents
[10m] The most prominent use of Grignard reagents is in the Grignard reaction, in which a Grignard reagent attacks this functional group.
ANSWER: carbonyl [or aldehyde; or ketone]
[10h] This palladium- or nickel-catalyzed cross-coupling combines a Grignard reagent and an organic halide. This reaction is used to synthesize polyalkylthiophenes, which are used in organic solar cells and OLEDs.
ANSWER: Kumada coupling [or Kumada–Corriu coupling]
