The coupling of aryl bromides or iodides with oxindoles using a copper iodide-N,N′-dimethylethylene diamine system is presented. The reaction proceeds efficiently and tolerates a variety of substitution patterns.

N-Phenyl-p-benzoquinoneimine N-oxide is generally unreactive in 1,3-dipolar cycloaddition reactions, but with acetylenedicarboxylate esters it gives indolones, formed from the initial adducts by a rearrangement which entails an alkoxycarbonyl migration.The analogous nitrone derived from anthraquinone gives unrearranged adducts with a variety of 1,3-dipolarophiles; monosubstituted alkynes and alkenes give 4-substituted-isoxazolines and -isoxazolidines.Fluorenoneimine N-oxide behaves similarly.We also describe some reactions of diphenylcyclopropene which were performed in an attempt to prepare cyclopropenoneimine N-oxides.
