Abstract

Abstract The synthesis and properties of a series of nine new 4, 6-diphenyl-1, 9- anthrazolines molecules 1a–1i are reported. Compounds 1a–1i were synthesized by Friedländer condensation of 4, 6-dibenzoyl-1, 3-phenylenediamines and acetyl- functionalized compounds in the presence of polyphosphoric acid as catalyst, in yields ranging from 60% to 94%. The 4, 6-diphenyl-1, 9-anthrazolines are thermally robust with ...
