In the retrosynthetic analysis of 1-phenylbutan-1-one (C₆H₅COCH₂CH₂CH₃, also known as butyrophenone), which of the following represents the most logical synthetic disconnection using the Friedel-Crafts acylation strategy? (Consider the directness of the approach, the regioselectivity of electrophilic aromatic substitution, and the compatibility of the reagents.)
The Suzuki coupling reaction between bromobenzene and phenylboronic acid in the presence of a base and a Pd(0) catalyst yields:
The Norrish Type II reaction of pentan-3-one upon irradiation with UV light gives primarily:
The product of the Heck reaction between bromobenzene and methyl acrylate in the presence of Pd(OAc)₂, PPh₃, and a base is:
The Suzuki coupling reaction between bromobenzene and phenylboronic acid in the presence of a Pd(0) catalyst and base yields:
Which of the following aromatic compounds will NOT undergo Friedel-Crafts acylation under standard conditions (CH₃COCl, AlCl₃ catalyst)?
When formaldehyde (HCHO) and benzaldehyde (C₆H₅CHO) are treated with concentrated sodium hydroxide (NaOH) in a crossed Cannizzaro reaction, which of the following describes the major products and the regioselectivity of the hydride transfer? (Recall that in the Cannizzaro reaction, one molecule of aldehyde is oxidized to the carboxylate and another is reduced to the alcohol. In the crossed version, consider which aldehyde is more electrophilic and more likely to be attacked by OH⁻.)
The Perkin reaction is used for the synthesis of:
