Abstract

Neue Richtung: Die Carboxygruppe von Benzoesäuren steuert deren ortho-Acylierung mit Carbonsäureanhydrid in Gegenwart eines Rhodiumkatalysators (siehe Schema; cod=Cyclo-1,5-octadien). Diese ortho-Acylierung bildet eine Ergänzung zu der meta-Selektivität von Friedel-Crafts-Reaktionen. Die Produkte können durch Protodecarboxylierung in Arylketone überführt werden.
