A single-step synthesis of 4-hydroxy-functionalized bi-aryl and aryl/alkyl ketones via oxidative coupling of terminal alkynes with benzoquinones is reported. Furthermore, with naphthoquinones, owing to the cross-resonance of carbonyl with the aromatic ring, alkene-alkyne cycloaddition is more favored to give four-membered carbocyclic adducts, thereby precluding the requirement of preactivated alkynes.

Pd(0)-mediated coupling between iodoarenes, [11C]carbonmonoxide and aryltributylstannanes has been used to prepare simple model [11C]aryl ketones. Here, we aimed to label four 2-Aminoethylbenzofuran chemotype based molecules ([1
