A rapid and efficient single-step synthesis of substituted anilines has been developed. The aromatic nitro compounds were reduced by using reducing systems generated by the action of an excess of LiAlH4 on TiCl4. Anilines substituted with different functional groups were synthesized in high yields and purity starting from the corresponding nitro compounds. The developed procedure is applicable to nitroaromatics containing both electron withdrawing and electron donating substituents. Substrates with electron donor substituents require a larger excess of LiAlH4. The reducing power of the prepared reactant systems depends on the used molar ratio of LiAlH4 and TiCl4.
Azo coupling of o- and p-(dialkylaminosulfonyl)benzene-diazonium salts with 7-acetylamino-4-hydroxynaphthalene-2-sulfonic acid in citrate-phosphate buffer solution

Dependences of the partial rate constants for azo coupling of o-(dialkylaminosulfonyl)benzene-diazonium salts with 7-acetylamino-4-hydroxynaphthalene-2-sulfonic acid (N-Acetyl-I-acid) on the fraction of the dianionic form of the latter indicate considerable steric hindrances to the second stage of the reaction. Ionization of the hydroxy group of N-acetyl-I-acid gives rise to additional electrostatic repulsion at the stage of formation of the σ complex, which reduces the rate of azo coupling at the 3-position of orthanilic acid.
