ELEMENTAL SULFUR-CATALYZED SYNTHESIS OF N,N'-DISUBSTITUTED 1,3-DIIMINOISOINDOLINES FROM PHTHALONITRILE WITH AMMONIA AND AMINES

Article abstract of DOI:10.1246/cl.1984.1423

Various N,N'-disubstituted 1,3-diiminoisoindolines were synthesized by the elemental sulfur-catalyzed reaction of phthalonitrile with ammonia and some primary amines in excellent yields.Several functionalized isoindolines were also obtained in high yields
