Abstract

Phosgenation of p-aminobenzenesulfonamide (VII) in an inert medium at 150" gave p- isocyanatobenzenesulfonyl isocyanate (111), while at 90" the product was p- isocyanatobenzenesulfonamide (IX). Several derivatives of I11 were prepared illustrating the difference in the reactivity of the sulfonyl and phenyl isocyanate groups contained in this molecule. Organodisulfonyl isocyanates IV-VI were prepared by the direct phosgenation ...
