Methods and reagents for photo-initiated carbonylation with carbon-isotope labeled carbon monoxide using alkyl/aryl iodides with water pretreated by a base are provided. The resultant carbon-isotope labeled acids are useful as radiopharmaceuticals, especially for use in Positron Emission Tomography (PET). Associated kits for PET studies are also provided.

a radiochemical purity of 78 ± 7% d.c. The labelling agent 1-iodo-2-[11 C]methylpropane was coupled to thiophenol, phenol and phenylmagnesiumbromide. Average radiochemical conversions of 83% d.c. for thiophenol, 40% d.c. for phenol, and 60% d.c. for phenylmagnesiumbromide were obtained. In addition, [11 C]2-methyl-1-propyl phenyl sulphide was isolated with a radiochemical yield of 5 ± 1% d.c. and

[carboxyl-11C]Carboxylic acids were prepared from alkyl iodides via photoinitiated radical reactions using 10-8 mol of [11C]carbonmonoxide in binary and ternary homogeneous solvent mixtures. Short- (isobutyric), medium-, and long-chain saturated fatty acids (heptadecanoic) were labeled with isolated decay-corrected radiochemical yields ranging from 55% to 70% in 5−7-min reactions. The conversion of [11C]carbon monoxide
