Abstract: | ![]() Results are reported on the regioselective C‐deuteriation of a series of enol acetates (derived from the aryl alkyl ketones) using molecular deuterium as the D‐source and palladium‐on‐barium sulphate as the mediator. The results presented highlight potential problems associated with the deuteriation of enol acetates. Copyright © 2005 John Wiley & Sons, Ltd. |
