A regioselective direct arylation of arenes and olefins at the ortho position is reported. The key to the high selectivity is the appropriate choice of diaryliodonium salts as the arylating reagent in the presence of a cationic iridium(iii) catalyst. The coordination of the metal with an oxygen atom or a nitrogen atom and subsequent C-H activation allows for direct arylation with coupling partners. This reaction proceeds under mild reaction conditions and with a high tolerance of various functional groups including many halide functional groups.
Undirected arene and chelate-assisted olefin C-H bond activation: [Rh IIICp*]-catalyzed dehydrogenative alkene-arene coupling as a new pathway for the selective synthesis of highly substituted Z olefins

Undirected/Directed Cross-Coupling: A new dehydrogenative Rh III-catalyzed cross-coupling reaction between bromoarenes bearing no directing group and vinylic substrates substituted by a chelating group is reported. An original reaction mechanism enables the use of internal alkenes in a Z-selective coupling. The application of 1,3-disubstituted or 1,2-homodisubstituted arenes leads to the formation of highly functionalized, complex, and valuable olefins as one single isomer. Copyright

Stereoselective β-elimination of 2-chloro-3-hydroxyamides 1 is achieved by using samarium diiodide to yield α,β-unsaturated amides 2, in which the C=C bond is di- tri-, or tetrasubstituted. The starting compounds 1 are easily prepared by reaction of the c

The R*,S* and R*,R* diastereomers of N,N-diisopropyl-2,3-dideuterio-2-methyl-3-phenylpropanamide (5,6) have been used to investigate the diastereoselectivity of the β-lithiation of N,N-diisopropyl-2-methyl-3-phenylpropanamide (4).The β-lithiation of 4 is
