The present invention relates to a novel process for preparing alkoxyamines from a nitroxide and a dithiocarbamate by photolysis reaction.
This process, which does not generate effluent containing metals, may be carried out in batch or in continuous mode and takes place at a lower temperature than the known processes for synthesizing alkoxyamines.

Dithiocarbonate derivatives are disclosed, along with a process for preparing the same. The dithiocarbonate compounds can be utilized as initators, chain transfer agents and/or terminators in controlled free radical polymerizations. The dithiocarbonates can be used to produce polymers having narrow molecular weight distribution. Advantageously, the compounds of the present invention can also introduce functional groups into the resulting polymers. The dithiocarbonate compounds have low odor and are substantially colorless.
