An efficient rhodiumIII-catalyzed CâH activation and subsequent conjugate addition was achieved under mild conditions. The reaction utilized inert arenes to replace stoichiometric organometallic reagents and can tolerate various functional groups as well as air and water.
inexpensive and atom‐economical approach to CH bond functionalization, a cationic CoIII complex (see scheme) was used to generate nucleophilic organometallic species in situ without additional activating reagents. Under these conditions, aryl CH bonds underwent efficient addition to polar electrophiles, including α,β‐unsaturated N‐acyl pyrroles as β‐substituted ester and amide surrogates.
