Primary, secondary and tertiary enaminones react with bis(pyridine)iodonium(I) tetrafluoroborate in methylene chloride at room temperature to give α-iodo enaminones in almost quantitative yields. The reported reaction is the first known example of direct iodination of tertiary enaminones.

technologies (Python, OpenCV) was used to automate a gravity based in-line liquid-liquidextraction during the iodination of enaminones in continuous flow. The system was able to cope with significant colouration of the organic reaction stream and with significant volume/flow changes in the aqueous and organic phase streams due to extraction of the water soluble acetonitrile co-solvent.
