Three-component C–H bond additions across two different coupling partners remain underdeveloped. Herein, we report the first three-component RhIII-catalyzed C–H bond additions to a wide range of dienes and aldehydes. Our method constitutes a complementary access with Ellman's CoIII-catalytic system to homoallylic alcohols.

A mild mannered reaction: An ideal addition of “inert” arylCHbonds to CN groups has been achieved in the absence of any additives and without any undesirable by‐products (see scheme). The reaction can be carried out under mild conditions without the requirement of special techniques. Cp*=pentamethylcyclopentadienyl.
