The internal OH group of 1,2-propanediol is selectively removed in the deoxygenation catalyzed by [{Cp\*Ru(CO) } (ฮผ-H)] OTf (1, Cp\*=C Me , OTf=trifluoromethanesulfonate; see scheme). This reaction provides a model for deoxygenation of polyols derived from carbohydrates, for use in alternative, biom

The 2-dimethylamino-1,3-dioxolane derivatives of 1,2-diols when treated with trifluoromethane sulfonic anhydride and diisopropylethylamine in toluene give the corresponding olefins stereospecifically under mild experimental conditions. Many methods are known for the conversion of 1,2-diols into the
It was found that the deoxygenative coupling of alcohols efficiently proceeded by treatment with lanthanum metal and chlorotrimethylsilane in the presence of a catalytic amount of iodine. This coupling reaction was accelerated by the addition of a catalytic amount of copper(I) iodide.
Radical deoxygenation of alcohols and vicinal diols with N-ethylpiperidine hypophosphite both in alcohols and in water is described. S-Methyl dithiocarbonate and bis-S-methyl dithiocarbonate of carbohydrates and nucleosides were deoxygenated efficiently under reaction conditions.
