  An iodine-mediated formal oxidative cycloaddition of amidines with tertiary amines was first demonstrated in air. Both symmetrical and unsymmetrical 2,4-disubstituted 1,3,5-triazines were obtained in up to 85% yields. It is noted that a tertiary amine was employed as a one carbon synthon of 1,3,5-triazines and two C–N bonds were formed in one pot. Control experiments revealed that the reaction underwent
