Benzyl alcohols formed by the reduction of benzaldehydes, alkylarylketones, and benzophenones with sodium tetrahydridoborate in alcohols undergo in situ etherification with the solvent in the presence of a catalytic amount of HCl. Thus the process may be regarded as one-pot transformation of carbonyl compounds into the corresponding benzyl ethers. The yields of ethers depend on the substituent nature

Hydrodeoxygenation and reductive etherification of biomass-derived aldehydes were realized on the same Pd/TiO2 photocatalyst via photocatalytic transfer hydrogenation using aliphatic alcohols as hydrogen donor, and the selectivity was easily switched by the substrate concentration.
