Geminal mercapto trialkyl- and trialkoxy-silanes undergo an efficient radical chain rearrangement, whereby the silyl group migrates from carbon to sulfur; the starting materials are readily obtained by exploiting the peroxide initiated radical addition of dithiocarbonates (xanthates) to trialkyl- or trialkoxy-vinylsilanes.

The peroxide initiated radical addition of dithiocarbonates (xanthates) to trialkoxy vinylsilanes leads to functionalized trialkoxysilanes. Prior addition of the dithiocarbonates to an alkene before reaction with the vinylsilane can be used to increase the complexity of the final product.
