Abstract [en]

The enchanicing effect of several photsensitizers in photoinitiated radical carbonylation is demonstrated and applied to acceleate the synthesis of compounds labeled with short-lived 11C. With the sensitizers, the synthesis of [carbonyl-11C]esters and acids from alkyl iodides, [11C]carbon monoxides, alcohols, and water provided up to 75-85% decay-corrected radiochemical yields in 6-min reactions under mild conditions. Acetone was used as a sensitier in preparing 13C-substituted 1,10-decanedicarboxylic acid from (13C)carbon monoxide.
