Microwave Assisted Synthesis of Fluorinated Hexahydro 1,3,5‐Triazine Derivatives in Aqueous Medium and One Pot Synthesis of 1,2,4‐Triazolo(4,3‐a)1,3,5‐triazines
摘要:
A multi-component condensation of substituted phenylthiourea/urea, aqueous formaldehyde and substituted aromatic/heterocyclic amines lead to 2-thioxohexahydro-1,3,5-triazines (4) in aqueous medium under microwave irradiation in 30-60 sec in quantitative yield with reasonable purity. Further, triazolo[4,3-a]triazines were also prepared by a one-pot reaction of 'in situ' synthesized triazinyl hydrazine (7) with CS2 (9).
