It has been established that an electron-deficient CpRhIII complex, bearing two ester moieties on the Cp ring, [CpERhIII], catalyzes the aerobic oxidative cross coupling of substituted acrylamides with both activated and unactivated alkenes, leading to (2Z,4E)-dienamides, at relatively low temperature (80 °C). Importantly, tertiary, secondary, and primary amide directing groups could equally be used

Exposure of aromatic carboxamides 1e-1m, heteroaromatic carboxamides in-1p, and alpha,beta-unsaturated carboxamides 1q-1s to 1,1-dimethylallene in the presence of the a cationic iridium complex derived from [Ir(cod)(2)]BAr4F and rac-BINAP results in direct C-H prenylation to furnish adducts 2e-2m, 2n-2p, and 2q-2s, respectively, in good isolated yields as single isomers.
Amide-Directed Alkenylation of sp<sup>2</sup> C−H Bonds Catalyzed by a Cationic Rh(I)/BIPHEP Complex Under Mild Conditions: Dramatic Rate Acceleration by a 1-Pyrrolidinecarbonyl Group
A cationic rhodium(I)/BIPHEP complex catalyzes amide-directed regioselective alkenylations of olefinic or aromatic sp(2) C-H bonds in good yields under mild reaction conditions. The use of a 1-pyrrolidinecarbonyl group as a directing group dramatically accelerates the reaction.
