Synthesis of 2-Imidazolidinones Through Reaction of N-Arylsulfonylaziridines with Alkyl and Aryl Isocyanates in the Presence of Sodium Iodide.-The title reaction is a mild and convenient method for the regio-and stereoselective preparation of 4-aryl and 4-alkyl substituted 2-imidazolidinones. The reaction is insensitive to the effect of substituents on the 2-phenyl group of (I). -(NADIR, U. K.; BASU, N.; SHAIHLA; Indian J.

ChemInform Abstract The trisubstituted s-triazines (VII) are formed by consecutive substitution of the chlorine atoms of cyanuric chloride (I) with the anilines (II), (IV), and (VI).

Reaction of m‐nitroaniline (I) with the trichlorotriazine (II) gives the dichlorotriazine (III) which is further coupled with the trifluoromethylaniline (IV), producing the bis(arylamino)triazine (V).
