Tripod-like compounds: Syntheses of tris(p- or o-amino phenoxymethyl)-propane, tris(p- or o-amino phenoxyethyl)amine, and their Schiff base or salicyl derivatives

Tris(nitrophenoxymethyl)propane and tris(nitrophenoxy ethyl)amine, prepared by the reaction of trimethylol propane or triethanol amine with p- or o-ch loronitrobenzene, were reduced to give the corresponding amines. The amines condensed with 2-pyridinecarboxaldehyde, 2-quinolinecarboxaldehyde, or sal icylaldehyde to give the tripod Schiff bases. The tripodal salicylamides we re obtained by condensation of salicylic acid with the amines in the presen ce of phosphorus trichloride.
