Abstract
In this paper, we report a facile and efficient method for the synthesis of 1,3,5-tris-arylhexahydro-1,3,5-triazines by reaction of formaldehyde and aromatic amines catalyzed by triethylamine (Et3N) and assisted by ultrasound at room temperature. This method has the advantages of short reaction times, good yields and mild reaction conditions.
