A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 5509-65-9, Name is 2,6-Difluoroaniline, molecular formula is C6H5F2N. In an article, author is Mogilaiah, K.,once mentioned of 5509-65-9, Recommanded Product: 2,6-Difluoroaniline.
An efficient, practical and eco-friendly method for the synthesis of 2,8-di(3-aryl[1,8]naphthyridin-2-yl) 1,2,3,4,6,7,8,9-octahydropyridazino [4,5-g]phthalazine-1,4,6,9-tetraones 3 by the condensation of 3-aryl-2-hydrazino-1,8-naphthyridines 1 with pyromellitic dianhydride 2 in 2:1 molar ratio in the presence of catalytic amount of DMF under microwave irradiation/ in presence of catalytic amount of PTSA in the solid state at RT under grinding conditions is described. The structural assignments to compounds 3 are based on their elemental analyses and spectral (IR and H-1 NMR) data. The compounds 3 have been evaluated for their antibacterial activity.
