INFLUENCE OF THE REACTION CONDITIONS ON THE REDUCTION OF NITROBENZENE CATALIZED BY POLY (4-VINYLPYRIDINE) ANCHORED [RH(COD)(2-PIC)2](PF6) COMPLEX

Reported here are the influence of the reaction conditions variation (carbon monoxide pressure, P(CO), rhodium content, [Rh], and temperature) on the catalytic reduction of nitrobenzene to aniline by [Rh(COD)(2-pic)2](PF6) (COD = 1,5-cyclooctadiene, 2-pic = 2-picoline) immobilized on poly(4-vinylpyr...
