Pd(0)-catalyzed carboiodonation of but-3-enylcarbamic chloride has been developed with NaI as additive, which provides a ready access to substituted gamma-lactam bearing an alkyl iodide group. This reaction features alkyl iodide reductive elimination as a key step in catalytic cycle, indicating the crucial role of additive NaI. (C) 2014 Elsevier Ltd. All rights reserved.
