Aryloxy radicals from diaryloxydiazirines: alpha-cleavage of diaryloxycarbenes or excited diazirines?
The synthesis of diaryloxydiazirines, precursors to diaryloxycarbenes, is described. Thermolyses of the diazirines afford anticipated carbene products, but photolyses afford both carbenes and aryloxy radicals by alpha-scission. UV spectra of the carbenes and radicals are observed.
