suitable thioesters represents a mild method for the formation of carbon-carbon bonds and the formation of 1,3-dicarbonyl compounds. A study of the scope and limitations of this reaction for the synthesis of these or mixed 1,3-carbonyl/thiocarbonyl compounds by a base promoted sulfur abstraction rearrangement is described. These reactions were typically very clean and the products were obtained in good

1,3-Dienes were prepared from 1,4-ketoxanthates, obtained by the radical addition reaction of an S-(2-oxoalkyl) xanthate to a terminal olefin, through the DBU induced thermalelimination of sulfurdioxide from the derived 2-sulfolenes.

Treatment of a geminal pivaloxy xanthate, prepared by an intermolecular radical addition of a xanthate to vinyl pivalate, gives a 1,3-dithietanone, a little known class of compounds.

Three convergent routes to thiophenes are described, hinging on the radical addition of alpha-xanthyl ketones to ethyl vinyl sulfide or to vinyl pivalate. The latter route ultimately proved to be the most versatile and efficient (61-94%).
