Abstract
An efficient generation of a stoichiometric amount of carbon monoxide by Zn-mediated reduction of oxalyl chloride can replace the use of excess toxic gaseous CO in palladium-catalyzed alkoxy-/amino-/hydrogen-/hydroxycarbonylation processes providing esters, amides, aldehydes, and carboxylic acids in very good yields.
