WebThe Graham oxidation of amidines to halodiazirines, coupled with the diazirine exchange reaction, makes available many new diazirine precursors of carbenes. Nitration of the phenoxy moieties of phenoxychloro‐ or phenoxyfluorodiazirine converts them to leaving groups, ultimately permitting the preparations of CCl2, CClF, and CF2.
