    Abstract: This specification discloses a process for the preparation of Beta -thiolactones whereby carbonyl sulfide is reacted with an ethylenically unsaturated compound in the presence of actinic radiation having a wave length between 2,800 and 3,600 Angstrom units. This process can be used to prepare known Beta thiolactones and novel perhalogenated Beta -thiolactones which are useful as monomers for the preparation of polyesters as well as chemical intermediates for the preparation of thiocarboxylic acids or their ester and amide derivatives.
