-
A.
Suzuki coupling
chosen
Suzuki coupling is a widely used palladium-catalyzed cross-coupling reaction that forms carbon–carbon bonds between organoboron compounds and organic halides, fundamental in organic synthesis and pharmaceutical chemistry.
-
B.
Buchwald–Hartwig amination
The Buchwald–Hartwig amination is a palladium-catalyzed cross-coupling reaction that forms carbon–nitrogen bonds by coupling aryl (or vinyl) halides with amines, widely used in the synthesis of pharmaceuticals and fine chemicals.
-
C.
Robinson annulation reaction
The Robinson annulation reaction is a classic organic chemistry transformation that forms six-membered rings by combining a Michael addition with an intramolecular aldol condensation, widely used in the synthesis of complex cyclic molecules and natural products.
-
D.
Eschenmoser sulfide contraction
Eschenmoser sulfide contraction is an organic rearrangement reaction that converts certain sulfur-containing intermediates into carbonyl compounds, widely used in complex molecule and natural product synthesis.
-
E.
Williamson construction
Williamson construction is a classical combinatorial method for building large Hadamard matrices from smaller symmetric matrices with special algebraic properties.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
