Three COmponent -arylation: A carbonylative ketone -arylation process employing acetone for the first time, as well as acetophenones, is described (see scheme). The reaction tolerates a range of (hetero)aryl iodides and several functionalised aryl ketone coupling partners. Only low pressures of molecular CO are applied and no additional solvent is necessary.

A mild and highly efficient method for the preparation of carboxylic acids is developed through a visible-light-mediated aerobic oxidative cleavage of β-diketones. This process provides a potential general, practical and scalable protocol for both laboratorysynthesis and industrial production of carboxylic acids in a green manner.
