efficiently prepared by dehydration of [11C]carbamate salts, which in turn are easily formed from cyclotron‐produced [11C]CO2 and amines in the presence of a CO2 fixation agent. The [11C]isocyanates are useful radiosynthons for the synthesis of a variety of [carbonyl‐11C]‐labeled asymmetrical ureas and carbamate esters. The method is well suited to incorporate any isotope of carbon, and is especially
