Aryl triflates, methyl- or arylboronic acids, and a low concentration of [11C]carbon monoxide were employed on small scale in the syntheses of fifteen 11C-labelled ketones using palladium-mediated ...

11C-carbonylation followed by reductive amination. The 11C-carbonylation was performed in the presence of tetrakis(triphenylphosphine)palladium using aryl iodides or aryl triflates, [11C]carbonmonoxide and phenyl-/methylboronic acid. The [11C]ketones formed in this step were then transformed directly into amines by reductive amination using different amines in the presence of TiCl4 and NaBH3CN. The 11C-labelled
