Metal-Free Diaryl Etherification of Tertiary Amines by Ortho-C(sp2)-H Functionalization for Synthesis of Dibenzoxazepines and -ones

Article abstract of DOI:10.1021/acs.orglett.7b03328

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-
