The synthesis and the infrared and massspectra of diaryl and aryl alkyl sulfate diesters are described. The massspectra of these two classes of compounds consistently showed an intense molecular ion and two or three additional intense, diagnostic ions. Their infrared spectra also gave information useful for characterizing and differentiating these two classes of compounds.
A process is described for preparing dioxazine derivatives of the formula (1)
and corresponding intermediates.
