Site-selective carbonylation of arenes via C(sp2)-H thianthrenation: Palladium-catalyzed direct access to α,β-unsaturated ketones
palladium-catalyzed carbonylative Heck reaction of aryl thianthrenium salts with carbon monoxide and alkenes has been developed. This protocol can greatly reduce the quantity of olefins used in the carbonylative Heck reaction. In addition, the reaction can also proceed when the coupling partner is a non-activated olefin which is not common in such carbonylative Heck reactions. Combined with C–H thianthrenation
1‐Arylvinyl formates as a kind of new CO surrogate have been explored for the first time. Most of the known CO precursors usually produce undesired residuals, which have to be removed. In this strategy, after CO release, the in situ generated acetophenones from 1‐arylvinyl formates can be successfully applied as a good ketone source in the synthesis of chalcones with benzaldehydes via a palladium‐catalyzed

A chemoselective cascade cycloaddition reaction is developed for green and efficient access to cyclopenta[c]pyridine derivatives. Simple and inexpensive NaOH is used as the sole catalyst for this process. The δ-carbon of cyclopropyl ester is activated as a nucleophilic carbon to initiate highly chemoselective cascade reactions. Cyclopenta[c]pyridines bearing various substituents are afforded in excellent
