Abstract

At T≥ 140° C, different primary aromatic amines (pX–C6H4NH2; X= H, OCH3, CH3, Cl) react with both ethylene-and propylene-carbonates to yield a chemoselective N-alkylation process: bis-N-(2-hydroxyalkyl) anilines [pX–C6H4N (CH2CH (R) OH) 2; R= H, CH3] are the major products and the competitive formation of carbamates is substantially ruled out. At 140° C, under solventless conditions, the model reaction of aniline with ethylene ...
