Abstract:
We have developed a palladium-catalyzed ester carbonylation reaction that enables the synthesis of ester-substituted benzofuran derivatives in a single step through the introduction of alkyl halides undergoing in situ hydrolysis and alkynyl aryl iodides. This method demonstrates broad applicability to both primary and secondary alkyl halides while maintaining excellent functional group compatibility under low palladium loading conditions. Notably, this strategy significantly expands the scope of the ester carbonylation reactions.

During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
