  • Title: Photoinitiated free radical carbonylation enhanced by photosensitizers.
    Author: Itsenko O, Långström B.
    Journal: Org Lett; 2005 Oct 13; 7(21):4661-4. PubMed ID: 16209504.
    Abstract:
    [reaction: see text] The enhancing effect of several photosensitizers in photoinitiated radical carbonylation is demonstrated and applied to accelerate 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 monoxide, alcohols, and water provided up to 75-85% decay-corrected radiochemical yields in 6-min reactions under mild conditions. Acetone was used as a sensitizer in preparing 13C-substituted 1,10-decanedicarboxylic acid from (13C)carbon monoxide.
