The present invention relates to a process for preparing substituted biphenylanilides of the formula I
which comprises reacting a compound of formula II
in the presence of a base and of a palladium catalyst selected from the group of: a) palladium-triarylpliosphine or -trialkylphosphine complex with palladium in the zero oxidation state, b) salt of palladium in the presence of triarylphospine or trialkylphosphine as a complex ligand or c) metallic palladium, optionally applied to support, in the presence of triarylphosphine or trialkylphosphine, in a solvent, with a diphenylborinic acid according to formula (III)
Newly designednicotinamidederivatives were synthesized and characterized using spectral techniques (IR, 1H-NMR, 13C-NMR, and MS). Moreover, these compounds are investigated computationally. B3LYP/6–31 + G(d,p) level is selected as the calculation level in this study. Experimental and calculated IR spectrum were compared to each other. Electronic properties of synthesized compounds are examined using
