Abstrakt: [1-(11)C]Acetyl chloride ([(11)C]AcCl), an important [(11)C]acylating agent, was synthesized by reacting [(11)C]CO(2) with methylmagnesium bromide coated on the inner surface of a polyethylene loop (loop method). By optimizing the reaction conditions and synthesis parameters, [1-(11)C]phenylacetate and [1-(11)C]benzylacetate were produced from [(11)C]AcCl in high radiochemical yield and specific activity.
