Reductive radical addition of alkyl halides to ketene dithioacetal monoxide in the presence of tributyltin hydride and a radical initiator provides the corresponding adducts, 2-alkyl-1,3-dithiane monoxides, in good yields.
Radical Addition of Alkyl Halides to 2-Methylene-1,3-dithiane Monoxide as a Ketene Equivalent
Radicaladdition reaction of alkyl halides with ketene dithioacetal monoxide in the presence of tributyltin hydride and a catalytic amount of 2,2'-azobis(isobutyronitrile) (AIBN) proceeds smoothly to provide the corresponding adducts in moderate to high yields.
