Herein, we report a palladium-catalyzed dehydrogenative cross-coupling of indoles with cyclic enones to give β-indolyl cyclic enones under mild and neutral reaction conditions. The key to the success is to explore a mild condition, which ensures the indole C-H activation and subsequent syn β-hydride elimination through rapid enolization isomerization of Pd(II)-enolate while suppressing other undesired side reactions. Synthetic utility has also been demonstrated in the flexible transformation of the coupling products to meta-phenols and benzo[a]carbazoles.

Monoselective γ-C-H olefination and carbonylation of aliphatic acids has been accomplished by using a combination of a quinoline-based ligand and a weakly coordinating amide directing group. The reaction provides a new route for constructing richly functionalized all-carbon quaternary carbon centers at the β-position of aliphatic acids.
Structure elucidation of N-aryl-2-chloro-3-oxobutanamides with respect to intra- and intermolecular hydrogen bonding

In general, N-aryl-2-chloro-3-oxobutanamides form in solid state an intermolecular hydrogen bond between the anilide hydrogen and the anilide carbonyl oxygen of a neighbouring molecule, which is disrupted in solution. An intramolecular association could not be detected.
