Organic reactions in liquid crystalline solvents. 9. Investigation of the solubilization of guest molecules in a smectic (crystal-B) liquid crystal by deuterium NMR, calorimetry, optical microscopy, and photoreactivity methods
alkylation of aromaticketones with alkanes has been developed using a nickel catalyst with oxamide as the ligand. Acetophenones bearing electron-withdrawing substituents were functionalized directly with simple alkanes with high para-selectivity while acetophenones with electron-donating groups were mainly para-functionalized. A mechanistic study indicated that C-H bond activation of the aromatic ring may
