Die direkte oxidative Kreuzkupplung von Naphthalinen oder anderen elektronenreichen Arenen mit Mesitylenen durch hypervalente Iod(III)-Reagentien ergibt hohe Ausbeuten. Entscheidend sind dabei die selektive Bildung der Radikalkationen aus den Naphthalinen und der Einsatz von Mesitylenen als reaktive Nucleophile, die kaum zur Dimerisierung neigen. R = Alkyl, Aryl, Halogen, Estergruppe, Alkoxy usw.
