We report a catalytic method for the direct deoxygenation of various C–O bond-containing functional groups. Using a Ni(II) pre-catalyst and silane reducing agent, alcohols, epoxides, and ethers are reduced to the corresponding alkane. Unsaturated species including aldehydes and ketones are also deoxygenated via initial formation of an intermediate silylated alcohol. The reaction is chemoselective for
Propionic acid derivatives having the formula ##STR1## wherein X represents an oxygen or two hydrogen atoms, Y represents CH or N, A represents an oxygen or sulfur atom, and R represents hydroxy, amino, or a lower alkoxy group having 1 to 5 carbon atoms are antiinflammatory agents.
