Pd/C-Catalyzed Regiodivergent Hydrocarboxylation and Esterification of Alkynes An unprecedented and highly reactive Pd/C catalytic system has been introduced for regiodivergent hydrocarboxylation of terminal alkynes to selectively afford various acrylic and cinnamic acids employing oxalic acid as CO source as well as a promoter for the formation of active Pd-H complex.

Supported Pd-catalyzed ring opening and chemoselective aminocarbonylative coupling of benzoxazoles with aryl iodides† A tandem approach using polystyrene-supported palladium (Pd@PS) nanoparticles (NPs) catalyzed aminocarbonylative coupling of benzoxazole with aryl iodides to synthesize N-(2-hydroxyphenyl)benzamides has been devised. This protocol involves the ring opening of benzoxazole to 2-aminophenol followed by aminocarbonylative coupling with aryl iodides.
