- Polyfluorinated functionalized m-terphenyls. New substituents and ligands in organometallic synthesis
-
The synthesis and structural characterization of polyfluorinated arenes 2,4,6-(C6F5)3C6H2X and 2,6-(C6F5)2-4-BrC6H2X (X = NO2, Cl, Br) obtained in the Ullmann-type cross coupling reaction is reported. The nitro derivatives were reduced to the aromatic amines. The α-diimine [2,4,6-(C6F5)3C 6H2NCMe]2 and 2,4,6-(C6F 5)3C6H2I were obtained in condensation and Sandmeyer reactions, respectively, from the corresponding amine. The syntheses of 2,4,6-(C6F5)3C 6H2NHC(O)H, 2,4,6-(C6F5) 3C6H2NC, and 2,4,6-(C6F 5)3C6H2Si(X)Me2 (X = H, F, Cl) are also described.

- A convenient method for the oxidation of aromatic amines to nitro compounds using tetra-n-alkylammonium bromates
-
Tetra-n-propyl and tetra-n-butylammonium bromates were used for the oxidation of a variety of aromatic amines to nitro compounds. Reaction condition and recovery simple and yield of products high.

- Synthesis of Polyfunctionalized Biphenyls as Intermediates for a New Class of Liquid Crystals
-
A series of hexa- and octasubstituted biphenyls containing halogen, amino, nitro, and propylthio substituents were prepared by metal-mediated convergent synthesis from halobenzene precursors. The Pd-assisted C-C coupling methods were ineffective in the fo

- Aprotic diazotization in the presence of cuprous cyanide
-
In a procedure of extreme simplicity and rapidity a mixture of an aromatic primary amine, copper (I) cyanide and an alkyl nitrite in dimethyl sulphoxide yielded fair to moderate yields of the corresponding nitriles. Side processes observed were reduction (NH2&[H), nitration (NH2←NO2) and hydroxylation (NH2&[OH). In the case of polyhaloanilines halogen dance products could be detected.
