The research describes a practical method for the reductive cleavage of the sulfide bond in xanthates, with the purpose of removing the xanthate group from various synthetic targets that do not contain sulfur. The process involves heating xanthates in 2-propanol in the presence of equimolar amounts of dilauroyl peroxide, which is added in small portions. This method is advantageous because it does not require high dilution or slow addition of reagents, unlike traditional stannane-based radical reactions. The study concludes that this approach is efficient, particularly for secondary xanthates, and demonstrates tolerance to a variety of functional groups commonly encountered in organic synthesis. However, limitations were observed with primary xanthates, where large amounts of peroxide were needed and yields were poor.
