intramolecular N−O bond formation and the competitive Tiemann-type rearrangement via oxadiazolones as cyclic nitrenoid precursors were developed. Selectivity for the two isomers was remarkably influenced by steric and electronic effects, but tetrabutylammonium chloride (TBACl) was discovered as an effective additive to promote the Tiemann-type rearrangement over N−O bond formation.
