Abstract

IN the course of work on the properties of arylimino diaryl carbonates, we have found that phenylimino diphenyl carbonate (I)1,2,3 rearranges quantitatively to phenyl diphenyl carbamate (II)4 on heating at 330° for one hour, or on slow distillation at c. 360°. No by-products could be detected, and no indication of reversibility of the rearrangement could be found.
