Gram-Scale Ketone Synthesis by Direct Reductive Coupling of Alkyl Iodides with Acid Chlorides.

Alkyl aryl ketones were prepared on a gram scale by the nickel-catalyzed reductive coupling of alkyl iodides with aroyl chlorides. When scaled up 30-fold, this reaction shows a comparable coupling efficiency to the previously reported reaction performed under smallscale conditions. The mild and convenient reaction conditions show excellent tolerance to a range of functional groups and provide the ketones in good to excellent yields [ABSTRACT FROM AUTHOR]
