A rhodium(III)-catalyzed aerobic oxidative cross-coupling of acrylamides with unactivated alkenes via vinylic C-H activation has been developed. The present cross-coupling reaction was examined with a variety of differently functionalized acrylamides and unactivated olefins. In these reactions, highly valuable amide-functionalized butadienes were prepared in good to excellent yields. This protocol was also compatible with Weinreb amides. A possible reaction mechanism involving the chelation-assisted vinylic C-H activation via a carboxylate-assisted deprotonation pathway is proposed.

Herein, the regio- and stereoselective iodination, along with some examples for the bromination, of readily available acrylamides to access a variety of differently substituted Z-haloacrylic acid derivatives is reported. The reaction proceeds under mild conditions via a Rh(III)-catalyzed C-H-activation/ halogenation mechanism and represents a rare example of a direct halogenation of electron-poor acrylic acid derivatives.
SYNTHESE REGIOSPECIFIQUE D'AMIDO-1 VINYL-2 CYCLOPROPANES A PARTIR DE LITHIENS ALLYLIQUES MONOHALOGENES ET D'AMIDES TERTIAIRES α-ETHYLENIQUIES

Chloroallyllitium and gem-chloro(methyl)allyllithium readly react, via conjugated addition and cyclisation, with α-ethylenic aliphatic tertiary amides to produce, in a "one-pot" reaction, alkyl-substituted 1-amido-2-vinylcyclopropanes.
