Nitrogen and Oxygen Donors in Nonlinear Optical Materials: Effects of Alkyl vs Phenyl Substitution on the Molecular Hyperpolarizability

“…4-Nitroaniline ( 1 ), N -methyl-4-nitroaniline ( 2 ), N -phenyl-4-nitroaniline ( 4 , 4-nitrodiphenylamine), 4-nitrophenol ( 6 ), O -methyl-4-nitrophenol ( 7 , 4-nitroanisole), and O -phenyl-4-nitrophenol ( 8 , 4-nitrodiphenyl ether) were purchased from Aldrich and purified by column chromatography prior to use. N , N -Dimethyl-4-nitroaniline ( 3 ), 4-nitrotriphenylamine ( 5 ), and 4-amino-4‘-nitrobiphenyl ( 9 ) were synthesized using literature procedures.…”

1,2-Eliminations in a Novel Reductive Coupling of Nitroarenes to Give Azoxy Arenes by Sodium Bis(trimethylsilyl)amide

“…Current interest in azoxy compounds is increasing dramatically because of their physiological activities and applications to liquid crystals. − They are also utilized as DNA cleavers, polymerization inhibitors, stabilizers, dyes, and analytical reagents . Azoxy compounds can be prepared from amines, , hydroxylamines, , nitrosohydroxylamine ammonium salts, and azo, , nitro, − and nitroso compounds. , Those methods often require reducing agents, oxidizing agents, or UV light.…”
