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

A process for the production of phenylalkanes comprising a reaction for alkylation of at least one aromatic compound by at least one hydrocarbon fraction that is directly obtained from the Fischer-Tropsch process comprising linear olefins that have 9 to 16 carbon atoms per molecule and oxygenated compounds is described. Said alkylation reaction is carried out in a catalytic reactor that contains at least one reaction zone that comprises at least one acidic solid catalyst, and said hydrocarbon fraction does not undergo any purification treatment prior to its introduction into said reaction zone.

An unprecedented TfOH-catalyzed transferhydrogenation reaction has been developed using 1-tetralone as a novel dihydrogen source. Various alkenes, as well as triphenylmethyl and diphenylmethyl derivatives, have been successfully employed in this transferhydrogenation reaction, resulting in the formation of various desired products with good yields. Deuteriumlabeling experiments show that the α-hydrogen
