Rapid and Efficient Conversion of (CO2)-C-11 to (CO)-C-11 through Silacarboxylic Acids : Applications in Pd-Mediated Carbonylations

• Herein, we present a new rapid, efficient, and low-cost radiosynthetic protocol for the conversion of (CO2)-C-11 to (CO)-C-11 and its subsequent application in Pd-mediated reactions of importance for PET applications. This room-temperature methodology, using readily available chemical reagents, is carried out in simple glass vials, thus eliminating the need for expensive and specialized high-temperature equipment to access (CO)-C-11. With this fast and near-quantitative conversion of (CO2)-C-11 into (CO)-C-11, aryl and heteroaryl iodides were easily converted into a broad selection of biologically active amides in radiochemical yields ranging from 29-84 %.
