[reaction: see text]. A new method for efficient radical deoxygenation of alcohols is described for preparing bulk chemicals avoiding scale-up problems. Treatment of various thiocarbonyl derivatives with (Bu(4)N)(2)S(2)O(8) and HCO(2)Na in DMF afforded the corresponding deoxygenated products in excellent yields. The deoxygenation appears to be initiated by the transfer of a single electron to thiocarbonyl

Trifluoromethyl ether and difluoro(methylthio)methyl ether of phenols and aliphatic alcohols were selectively synthesized from the corresponding dithiocarbonates. When IF5-pyridine-HF was used alone in the reaction of the dithiocarbonate, the difluoro(methylthio)methyl ether was selectively formed. On the other hand, by the additional use of Et3N-6HF with IF5-pyridine-HF, trifluoromethyl ether was

Various S-methyl dithiocarbonates of tertiary and secondary alcohols are readily deoxygenated in high isolated yields by radical deoxygenation with di-n-butylphosphine oxide and various radical initiators in boiling dioxane. Primary alcohols react similarly in boiling xylenes.
