A cationic ruthenium(II)‐complex was utilized in the efficient synthesis of phthalimide derivatives by CHactivation with synthetically useful amides. The reaction proceeded through a mechanistically unique insertion of a cycloruthenated species into a CHet multiple bond of isocyanate. The novel method also proved applicable for the synthesis of heteroaromatic unsymmetric diamides as well as a potent
An efficient Rh(III)-catalyzed aerobic oxidative C–H alkenylation of arylamides with unactivated alkenes is described. The olefination reaction was compatible with various substituted arylamides including primary, secondary, and tertiary as well as functionalized unactivated olefins. Meanwhile, ortho mono/bis-alkylated arylamides were synthesized in the reaction of arylamides with norbornene. In the
