An iron-catalyzed sustainable, economically affordable, and eco-friendly synthetic protocol for the construction of various trisubstitutedpyrimidines is described. A wide range of trisubstitutedpyrimidines were prepared using a well-defined, easy to prepare, bench-stable, and phosphine-free iron catalyst featuring a redox-noninnocent tridentate arylazo pincer under comparatively mild aerobic conditions

Herein we report an iron‐catalyzed multicomponent dehydrogenative functionalization of alcohols to pyrimidines under atmospheric conditions. Using a well‐defined Fe(II)‐complex featuring redox noninnocent 2‐phenylazo‐(1,10‐phenanthroline) ligand, as a catalyst, a wide array of 2,4,6‐trisubstituted pyrimidines were prepared via dehydrogenative coupling of primary and secondary alcohols with amidines
