In a Pd-catalyzed domino cyclization and carboxylation reaction for synthesis of a variety of carboxylic acids, chloroform was used as convenient and safe carbon monoxide source. Heck cyclization leads in situ to a neopentylpalladium species, that can efficiently be trapped by dichlorocarbene to form a series of carboxylic acids.
