    Sammanfattning : The usefulness of low concentrations (typically 10 to 100 µM) of [11C]carbon monoxide and aryl triflates as substrates in 11C-carbonylation using different nucleophiles in the presence of lithium bromide was investigated. The reactions were performed in a micro autoclave of 200 µL volume and catalysed (mediated) by palladium(0). LÄS MER
