Abstract 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 small-scale conditions. The mild and convenient reaction conditions show excellent tolerance to a range of functional groups and provide
Alkyl aryl ketones are important structures with applications in many areas of chemistry. Hence, efficient procedures for their production are particularly attractive. In this communication, a general and efficientcarbonylative cross‐coupling of aryl iodides and unactivated alkyl bromides is presented. By using a simple palladium catalyst, a series of alkyl aryl ketones were synthesized in moderate

Ni-catalyzed ketone formation through mild reductive coupling of a diverse set of unactivated alkyl bromides and iodides with particularly aryl acidanhydrides was successfully developed using zinc as the terminal reductant. These conditions also allow direct coupling of alkyl iodides with aryl acids in the presence of Boc(2)O and MgCl(2).
