✦ Synopsis

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