Anhydrides of real and hypothetical [hydroxy(R-O)iodo]benzenes.

The anhydrides of [hydroxy(methanesulfonato-O)]iodobenzene (HMIB) and [hydroxy(toluenesulfonato-O)]iodobenzene (HTIB) were prepared by drying acetonitrile solutions of the compounds. The anhydrides of the hypothetical compounds [hydroxy(chloroacetato)-O]iodobenzene and [hydroxy(iodoacetato)-O]iodobenzene were obtained from aqueous solutions. Crystallographic structures were obtained for the anhydrides, except that of HTIB.
