Abstract
Tris(nitrophenoxymethyl)propane and tris(nitrophenoxy ethyl)amine, prepared by the reaction of trimethylol propane or triethanol amine with p- or o-chloronitrobenzene, were reduced to give the corresponding amines. The amines condensed with 2-pyridinecarboxaldehyde, 2-quinolinecarboxaldehyde, or salicylaldehyde to give the tripod Schiff bases. The tripodal salicylamides were obtained by condensation of salicylic acid with the amines in the presence of phosphorus trichloride.
