efficient synthesis of aldehydes from acidchlorides with hydrosilanes as a reducing agent in the presence of a palladium catalyst has been achieved. A simple mixture of commercially available Pd(dba)2 and Mes3P as a catalyst realized the reduction of various acidchlorides including aliphatic acidchlorides and α,β-unsaturated acidchlorides to the corresponding aldehydes in good to high yields under

have been developed; however, extension of this reactivity to remote C-H functionalizations through large-ring rhodacyclic intermediates has yet to be demonstrated. Herein we report the first example of the use of a U-shaped nitrile template to direct Rh(III)-catalyzed remote meta-C-H activation via a postulated 12-membered macrocyclic intermediate. Because the ligands used for Rh(III) catalysts are
