A phenyliodine(III) diacetate mediated umpolung reactivity of the tertiary amines with suitably substituted o-hydroxybenzyl and phenyl groups is exploited to facilitate o-C(sp2)–H functionalization to afford diaryl ethers. The presence of an o-CHO and secondary amine functionalities in the resulting diaryl ether, generated in situ, were utilized for synthesis of dibenzoxazepines and dibenzoxazepinones
