AbstractA formal ethylene alkylarylation reaction with aryl halides and alkyl oxalates enabled by synergistic photoredox/nickel catalysis is reported. This protocol takes advantage of borates as a traceless activation group, achieving the formal ethylene difunctionalized products via a catalytic three-component 1,2-alkylarylation of vinyl borate followed by a base-assisted deborylation process. The mild conditions allow for excellent functional groups compatibility and broad substrate scope.

A transition metal-free formal synthesis of phenoxazine is presented. The key step of the sequence is a high-yielding O-arylation of a phenol with an unsymmetrical diaryliodonium salt to provide an ortho-disubstituted diaryl ether. This species was cyclized to acetylphenoxazine in moderate yield. The overall yield in the three-step sequence is 72% based on recovered diaryl ether. An interesting, unusually stable iodine(III) intermediate in the O-arylation was observed by NMR and could be converted to the product upon longer reaction time.
