Abstract

The development of a fast and novel methodology to generate carbon-11 carbon monoxide ([11C]CO) from cyclotron-produced carbon-11 carbon dioxide ([11C]CO2) mediated by a fluoride-activated disilane species is described. This methodology allows up to 74 % conversion of [11C]CO2 to [11C]CO using commercially available reagents, readily available laboratory equipment and mild reaction conditions (room temperature). As proof of utility, radiochemically pure [carbonyl-11C] N-benzylbenzamide was successfully synthesized from produced [11C]CO in up to 74 % radiochemical yield (RCY) and >99 % radiochemical purity (RCP) in ≤10 min from end of [11C]CO2 delivery.

9. AuI/AuIIICatalysis: An Alternative Approach for CC Oxidative Coupling

Author

Hopkinson, Matthew N., Gee, Antony D., and Gouverneur, Véronique

Abstract

When reacted in the presence of external oxidants, gold complexes are capable of catalyzing oxidative homo‐ and cross‐coupling reactions involving the formation of new CC bonds. Over the last few years, several cascade processes have been reported in which coupling is preceded by a gold‐mediated aryl CH functionalization or nucleophilic addition. These reactions combine the unique reactivity of gold with oxidative coupling, enabling the construction of CC bonds between coupling partners that are not easily accessed using alternative catalysts. In this Concept paper, the development of gold‐catalyzed oxidative coupling reactions is discussed focusing on CC bond‐forming reactions of broad synthetic appeal.
