The direct conversion of alcohols into long-chain alkanes is an attractive but extremely challenging approach for biomass upgrading. Here, we describe the highly selective deoxygenative coupling of aryl ethanols with primary alcohols to produce alkanes, using a bis-N-heterocyclic carbene iridium (bis-NHC-Ir) complex as the catalyst. Up to quantitative yields and selectivity with a broad substrate scope are attained in both homo- and cross-coupling reactions. Mechanistic studies reveal that the further synergistic hydrogenation of the alkene intermediates by the formate generated in situ in the presence of bis-NHC-Ir is crucial for alkane production.

The diastereomeric syn- und anti-(1,4)naphthalenophanes 1 and 2 were synthesized via 2-thia(1,4)naphthalenophane (8) and vapour phase pyrolysis of its sulfone 9.Photolysis of 1 and 2 at -23 deg C yielded the intramolecular cycloadducts 15 and 14 which at room temperature rearomatize to 1 and 2, respectively.
