Conditions for the rapid hydrolysis of chloroform to carbonmonoxide (CO) using heterogeneous CsOH·H2O are described. CO and 13CO can be generated cleanly and rapidly under mild conditions and can be captured either in or ex situ in palladium-catalyzedaminocarbonylationreactions. Utilizing only 1–3 equiv of CO allows for the aminocarbonylation of aryl, vinyl, and benzyl halides with a wide variety
