Abstract

Abstracts: [11C]Carbon dioxide ([11C]CO2) and [11C]carbon monoxide ([11C]CO) are 2 attractive precursors for labelling the carbonyl position (CO) in a vast range of functionalised molecules (eg, ureas, amides, and carboxylic acids). The development of radiosynthetic methods to produce functionalised 11C-labelled compounds is required to enhance the radiotracers available for positron emission tomography, molecular, and medical imaging applications. Following a brief summary of secondary 11C-precursor production and uses, the review focuses on recent progress with direct 11C-carboxylation routes with [11C]CO2 and 11C-carbonylation with [11C]CO. Novel approaches to generate [11C]CO using CO-releasing molecules (CO-RMs), such as silacarboxylic acids and disilanes, applied to radiochemistry are described and compared with standard [11C]CO production methods. These innovative [11C]CO synthesis strategies represent efficient and reliable [11C]CO production processes, enabling the widespread use of [11C]CO chemistry within the wider radiochemistry community.
